Abstract: Cutting apparatus with three blades, for trimming three sides of an inner book or the like, having a drive system which permits the simultaneous trimming of two opposed sides of the work closely followed by the trimming of the third side. Operation of the third cutting blade while the other two are still in motion is permitted by driving the simultaneously operated blades along a multi-directional orbital path.

Abstract: An overlay is applied to a substrate, for example in the manufacture of book covers, by serially wrapping the overlay around a first pair of oppositely disposed edges of the substrate, folding the corners of the overlay into the substrate and wrapping the overlay around the two remaining edges of the substrate. The first wrapping of the overlay around a pair of edges of the substrate is accomplished by feeding the substrate with the overlay adhered thereto through a wrapping station alternately in opposite directions and deflecting the overhanging portion of the substrate at the leading edge out of the path of motion so that these overhanging portions may be engaged by a wrapping tool.
