WP Master Window patcher - technical specifications

H+S WP Master Window Patcher Technical Specifications

Main Features found in Heiber + Schröder WP Master Window Patcher:

Controllability

The basic requirement for efficient production is the controllability of the window patcher.

The unique HEIBER + SCHRÖDER video support helps even untrained personnel to adjust and operate the machine efficiently and safely.

An extensive library, including photos, diagrams, and videos, provides operators with support in case of questions and problems.

Automatic notification reminds the personnel when maintenance is due.

Blank

The input of the three main blank parameters sets automatically all functions in the running direction and all sensors.

Recipe Management

The window patcher can be set automatically by using recipes. In addition, descriptions and photos can be saved when recording special settings.

Spare Parts Support and Camera

All window patcher spare parts can be identified by means of 3D exploded images, reducing production stops to a minimum. A movable camera facilitates communication with the user’s national service team, or HEIBER + SCHRÖDER support.

Integrated Manufacturing

Additional modules can create an automatic work flow between your die cutters, your WP
master window patcher, and your folder-gluers, reducing manpower and considerably reducing production costs.

Pre-Feeder

PF series pre-feeders handle pile heights of up to 600 mm, and are available in one and multiple lane versions. Movable on wheels, these pre-feeders are easy to combine with any window patcher.

Automatic Stacker

Placed behind the window patcher, the stacker builds accurately counted piles of windowed blanks and delivers them to a subsequent conveyor system.

Automatic Reel Change

By means of the optional patented HEIBER + SCHRÖDER splicers, stand still times for reel changes can be eliminated. Automatic brakes and dancer rollers ensure constant tension control during both production and reel changes.

Transfer Components

A wide range of components are available to meet customers’ requirements of automatic transportation to and from the window patcher.

  • Load conveyor for manual load of piles
  • Pile turner for automatic turning of piles upside down
  • Pile infeed for automatic transportation of piles into a pre-feeder
  • Transfer conveyor for automatic horizontal transportation of piles including buffer functions
  • Handling components for handling tasks like:
    • Two lanes to one
    • One lane to two
    • 900 direction change
    • Pile rotation

Continuous product innovation requires flexible manufacturing capabilities. With the modular concept of the WP master window patcher you are able to develop new ideas over and over again and to produce them efficiently. Installed machines can be retrofitted without difficulty and so can be adapted to new production conditions.

Units for integration into carton board folder-gluers or in-line processing machines complete the HEIBER + SCHRÖDER window patcher component range.
