Title: Folder for flat laundry items - ensures better folds with less noise and a simpler layout (DK 1.5.78)
Inventor: HERRMANN LUDWIG
IPC: B65H45/04
Filed: 1977-08-20
Abstract: A folding machine for flat textiles has a folding flap above a conveyor belt, >=1 clamping bar and >=1 pressure cylinder. By means of the cylinder, the flap is pivotted under control, from a position in which it receives the leading edge of the article to be folded to one where the edge is clamped between the flap and the bar, and is later released. During this operation, the flap is moved from a flat position whilst the item runs on with the conveyor, into an inclined one which assists the front edge to fall away. The bearing on which the flap pivots, the flap itself, the operating cylinder and the clamping bar can all be pivoted on a common axis. The front edge of the goods cannot be pulled out of line as the folding flap lifts into its steeper alignment. The number of moving parts is reduces so that noise is also less. The height of the machine above the conveyor is reduced.
