FOLDING MACHINE Russian patent published in 1995 - IPC

FIELD: plastic working. SUBSTANCE: folding machine has a drive mounted on a frame, bearing housings with a series of horizontal drive and non-drive shafts provided with profile making members, and shafts of intermediate pinions. The housings are split in horizontal plane, and are made in the form of bars with split plane located between horizontal shafts, and are installed so to enable the gap between profile making members to be adjustable. Intermediate insertion pieces are located along the plane of split; housings, profile making members, pinions, and intermediate insertion pieces are replaceable, machine pinion has large pitch. Housings in the machine may be turned over through 180 degrees, in so doing, the openings in the housings for horizontal shafts are non- symmetric through the height as to horizontal surfaces of a housing. The folding machine is provided with vertical driven and non-driven shafts with profile making members installed successively and in pairs on machine frame enabling change of interaxis distance. The shafts are kinematically linked with intermediate pinions. Profile making members are replaceable, and intermediate intermediate pinions of a large pitch and replaceable. EFFECT: wider process opportunities and range of products. 6 cl, 4 dwg
