Circular arc curvature prevents cover strip detachment by minimizing stress on the joint during insertion into the outer groove.
A multi-roller assembly cuts continuous ribbons and folds multiple-ply products using suction retention.
A sheet dispenser integrates a cutting device and folding mechanism to create folded parts in intermediate layers.
A suction roller uses movable feelers and thrust springs to selectively communicate bores with a permanent suction source.
Synchronizing endless belt speed with the moving surface reduces frictional resistance, eliminating phase shifts between folded regions for stable operation.
A longitudinal asymmetrical cut in a flexible tubular sheet enables sequential folding that keeps opening edges accessible upon unrolling.
Axial roller movement compensates for tape shifting to maintain consistent edge folding.
An inverted fulcrum design allows the folding blade to move perpendicularly, resolving mounting restrictions and enabling accurate sheet insertion.
