High Performance Window Patcher

Patented mono-belt vacuum blank transport for one or two lane operation, ensures excellent flatness of the blanks even when curved.

The system operates without vacuum channels, tubes, filters and eliminates maintenance.

Automatic reel change

Standstill times for reel change can be eliminated by a patented H+S splicer system (option). Constant web tension during operation and reel change is provided by automatically controlled brakes and dancer rollers.

High performance static discharge system for film material

Allows smooth operation even for film material with critical static load.

Integrated Manufacturing

H+S offers components for an automatic workflow, between die cutting and length folding process, which reduces manpower.


Placed in front of a window patcher, pre-feeders of the series PF will handle pile heights of up to 600 mm, available in one- and two-lane versions. Movable on wheels, these pre-feeders are easy to combine with any window patching machine.

Automatic stacker

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

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
