The Sherwood Group invests in window patching

The Sherwood Group has added a Heiber & Schröder WP 1100-2 Master, which cost the firm £200,000, which be installed at its 2,800sqm Nottingham plant in April and will replace an existing Kohmann F1120/2 window patcher. It has joined Komori B1 presses and a range of die-cutters and gluing lines at the site. The WP 1100-2 Master features a master-feeder that accommodates a larger variety of carton blank styles. It also enables four different run modes to achieve top speed and a minimum marking for each blank style.

Chief executive Jeremy Bacon said: “Our packaging business in volumes is growing by about 25% per annum, and this investment continues to support that growth, predominantly in the food market. It will probably give us productivity improvements of anywhere between 30% and 40%.”

The Sherwood Group’s has 90 staff in Great Britain and a turnover of £12m. Globally the group has 350 staff and a turnover of £30m., 23rd September 2014

Model Obaly adds third window patching machine

The solid board forming Czech company has added a Heiber+Schröder WP 1100 MASTER window patcher to its production line. One of its main advantages is its high productivity achieved by adding a pre-feeder and a semi-automatic unloader, plus an integrated quality control module. It is also equipped with a "3D" window (a corner window) gluing ability and produces perfect fold lines. This is achieved by heating the foil and shaping it on-line. This capability opens up further opportunities for utilizing the state-of-the-art machine for luxury packaging items., 1st November 2013

BCP Fluted Packaging Ltd. incorporates more window patchers and tray formers

“We are not a typical packaging manufacturer, 99% of what we make is bespoke,” says Alan McAulay, Managing Director of BCP Fluted Packaging. During the past six years BCP almost doubled in size, leading to investing in two extra Heiber+Schröder lines a window patcher and a tray former that adds to the company’s existing suite of similar machines. These investments were prompted by an increasing number of inquiries for hot-eat take-away food packs, including one from a major international retailer. BCP’s New Product Development team created a window patched tray in three sizes for this client. “The retailer loved the concept,” recalls Alan McAulay. “So, between them and a number of other new customers that were coming on-line at the same time, we found ourselves having to service substantial additional window patched and tray formed work.”

With window patching previously outsourced to trade finishers, Con Shea says that the time was right to bring the process in-house. “If you send this type of work out then you have to factor in the time and cost involved in getting your product to the finisher and back again, along with the cost of the windowing itself.”

The plant’s existing Heiber+Schröder tray formers had proven so successful that BCP was keen to explore the supplier’s range of window patchers. “We had built up a very good relationship with Heiber+Schröder after buying the first machine from them,” recalls BCP’s Technical Director, Alan Leeming. “Their machines and services seem to tick the boxes for us. When we make a decision to buy a piece of equipment then we ensure it delivers performance, quality, flexibility, and reliability, and that the supplier offers good support. Without those we can’t deliver the innovation and added value that our customers expect from us.”

The twin stream Heiber+Schröder WPS1100 window patcher chosen by BCP is designed for fast make-ready, high production speeds, and quick clean-down after the run. In addition, the machine is easy to use, freeing the operator to concentrate on production and quality. One example of this ease of use is the way the critical, but often time-consuming, task of setting the feeder is handled. To make the process quicker and simpler, Heiber+Schröder have developed an innovative feeder setting system called “Teach in”. The system requires the operator to simply press one button with the blank in position and means that it takes less than a minute to set the blank length in the feeder of the WPS1100.

To ensure quality, a patented mono-belt vacuum transfer system on the machine means that blanks always remain in register as they travel along the line and that the window is applied in precisely the right position every time. If for any reason there is an interruption in the supply of blanks, the belt will automatically drop down, which stops any glue from finding its way onto the print face of subsequent blanks. The WPS1100 can window patch blanks up to 1100mm in width and the blanks themselves can be made from corrugated substrates up to 5mm thick, or carton board between 220 and 600 gsm. In terms of film, the machine can apply windows made from PE, PS, PVC, PET, or one of several other such substrates.

Con Shea says that easier logistics and the cost savings made from no longer outsourcing BCP’s window patching are not the only benefits of installing the WPS1100. “By having the machine on the shop floor, our designers are getting to know what can be achieved with it and so they are increasingly able to offer up brand new ideas.”

Changing styles on tray forming equipment can be time-consuming. To overcome this, BCP invested in an additional Flex-tower for its first Heiber+Schröder CE1000 tray former, installed three years ago. This additional adjustable forming tower, which is complete with a separate adjustment frame with dummy electrical pushers, allows the operator to carry out the bulk of the setting for the next job off-line while the current job is running. When the first job completes, the operator simply unplugs and removes the Flex-tower in use on the CE1000, replacing it with the one set off-line. Using this system has reduced the make-ready time for BCP’s difficult substrates significantly and a single off-line unit can be shared between several CE1000 tray formers.

The twin stream version of the CE1000 tray former, as installed at BCP, can process up to 24,000 blanks an hour, handling corrugated substrates up to 1.5mm thick. Like the WPS1100 window patcher, the CE1000 tray former features a “Teach-in” feeder which means the job can be set without the need to measure the carton or to use cams. The CE1000’s PC command unit allows the operator to set parameters for the servo driven pushers, the precision control of which ensures a smoothly and accurately formed tray. Alongside the standard gluing capabilities of the CE1000, BCP have added an adhesive refill system and a hot melt unit to their machines, enabling the application of different adhesives that can range from standard glues to ovenable adhesives and microwavables, sometimes with cold glue and hot melt applied in combination., 8th February 2013

Bobst demonstrates H+S WPS 1100 window patcher

Bobst showcased and demonstrated Heiber +Schroeder WPS 1100 window patching and liner carton machine for the first time in an exhibition.

Sachin Patil of Bobst India, said: "WPS 1100 is an ideal machine for packaging firms involved in tea carton and masala carton manufacturing. Besides this, it is also suitable for ready to eat food cartons like McDonalds, KFC, and Dominos. (...) The machine consists of an unwind shaft with clamping cones and brake per lane, a web in-feed, a rotary cross cutter and an application cylinder. The cross cutter and the application cylinder are both provided with suction and blower air control for transportation of the window/lining material. Even during machine operation, the cut-off length of the material can be digitally set from minimum to maximum."

Bobst has installed 42 WPS 1100 machines in India. Heiber +Schroeder has installed more than 650 WPS 1100 window patching and lining cartons worldwide., 9th April 2010

BCP Fluted Packaging Ltd. boosts tray forming capacity

“Over the last two years, we have seen a huge increase in demand for ovenable paper trays in the UK and we receive several inquiries each week from bakery companies. ", said Brian Jones, Managing Director of BCP Fluted Packaging Ltd. (BCP). "As a result, we have had to invest in new equipment from Germany to cope with demand, and will probably need to expand our factory.”

From zero, two years ago, sales of these trays now represent a significant proportion of BCP’s revenue. To satisfy demand, BCP has installed a new, high performance, Heiber+Schröder tray forming line, multiplying capacity by four overnight. Brian Jones said, “Before we installed the new machine, the amount of tray- formed work we had won was threatening to overwhelm us. Just about everyone we spoke to recommended Heiber and Schröder equipment and their machine gives us higher productivity and the flexibility to handle a wide range of products.”, 1st November 2009

Waseema Packaging invests in new window patcher

The British company installed a WP1100 line to absorb increasing demand. At the time of the new purchase, the company’s previous window patcher was struggling to cope. “It was a bottom fed roller affair and was not easy to run. When we saw the way that the Heiber + Schröder equipment worked we realised it was a much better solution.”, says Waseem Akhtar.

The WP1100 window patching machine is designed for fast make-ready, high production speeds, and quick clean-down after the run. To make feeder setup quicker and easier, Heiber and Schröder have developed an innovative feeder setting system called “Teach in”. It takes less than a minute to set the feeder of the WPS110 window patcher and involves the operator simply pressing a couple of buttons. After that they just jog the machine until the end of the blank reaches the feeder gauge, press the “Teach-in” button again, and that’s it, the feeder is set.”

This window patching machine is that it detects variations in the slip factor of the varnish applied to cartons and compensates automatically. “Printers won’t admit it, but there can be huge variations in the amount of varnish applied during a print run,” says Bobst’s Lee Alton. “By compensating automatically for these variations, the WPS1100 ensures that every job runs at the highest speed possible rather than at the speed of the slowest performing blank.”

All the information the operator needs is on one screen of the control panel. In terms of film, the machine can apply windows made from PE, PS, PVC, PET, or one of several other such substrates. Using a patented mono-belt vacuum transfer system, the Heiber + Schröder machine ensures that even warped blanks remain in register as they travel along the line and that the window is applied in precisely the right position every time. “And if for any reason there is an interruption in the supply of blanks,” says Lee, “the belt will automatically drop down”.

There are no vacuum channels or vacuum tubes to be cleaned and no filters, all of which saves users time and money. The use of glue dams defines very specifically the area where the adhesive is to be used. This reduces the amount of adhesive consumed. The machine also has a special cleaning unit which means that the operator can clean out the system in just a couple of minutes.

“The Heiber + Schröder has been a brilliant machine for us,” says Waseem. “It’s very user-friendly, which was important for us as our old machine was difficult to set and run.” Film changeovers are particularly quick and easy on the WPS1100, says Waseem. “All you have to do is turn a valve, swap the film reels, and then turn the valve again. It really couldn’t be simpler.”

Having installed the Heiber + Schröder line, Waseema Packaging found that it was soon window patching much more product than it previously had. “We bought the WPS1100 to increase capacity, but once our customers realised we could cope with even more window patching, the work just rolled in. About 70% of the jobs we put through it are trade jobs for food and toiletries, with 30% being our own sweet box work.”
