Abstract
A machine for processing flat, flexible articles, such as leather, to soften them. The machine utilizes a pair of opposed undulating surfaced processing members having an advance and return movement superimposed on an up and down movement. The opposed processing members are disposed on each side of the article to be processed, and soften the article, as well as move the article along between the processing members.
Claims10
A machine for the processing of flat, flexible workpieces by means of two opposing processing members, between which the workpieces are guided through, and whose distance apart is periodically increased and decreased by a relative movement, whereby the workpieces intended for processing is pressed by an arrangement of projections fitted on at least one processing member into an arrangement of corresponding recesses on the other processing member, wherein both processing members execute a feed movement in the closed position, taking the workpiece with it, and in an opened position, by contrast, the processing members execute a return movement.
