Abstract: The invention relates to a free-wheel, in particular a pinch roller free-wheel or a pinch body free-wheel, comprising relatively-rotating elements arranged one within the other on a common axis, which form a gap, in which pinch elements, in particular pinch rollers or pinch bodies, are arranged such that a friction connection can be produced with the facing outer surfaces of the elements, by means of the pinch surfaces, whereby the free-wheel outer rim is covered by a ring of fibre-reinforced plastic and the external diameter of the ring of fibre-reinforced plastic is about 1.3 to 1.8 times the diameter of the external clamping surface.

Abstract: The present invention is directed to a device for separating a stack of flexible, planar material such as cloth, comprising a fixed set of pins and an adjustable set of pins, where the adjustable set of pins follows a downwardly curved path of motion to create a fold in the top layer of the stack of so that this layer may be conveniently lifted off without lower layers adhering to the top layer.
