Abstract: The invention relates to a label separating apparatus in which, of labels formed in rows and columns on a continuous substrate being transported along a line of transport, labels found good and labels found defective upon determination of their quality are transported separately. The invention seeks to ensure that all of a plurality of defective labels possibly extant in any one of the rows can concurrently be transferred without fail selectively onto a different line of transport. The apparatus includes a primary conveyer in which a continuous substrate 21A is transported having labels 22A-22D, which are spaced apart from each other by a given distance and arranged in rows and columns, formed thereon and peelably adhered thereto. The primary conveyer includes a transport turn-back member 12A for permitting labels 22A-22D for each row concurrently to peel off the continuous substrate 21.

Abstract: A form dampening roller driving apparatus in which to obviate a hickey a slip is caused to occur between a form dampening roller and a plate cylinder in their mutual area of contact by rotationally driving the form dampening roller and the plate cylinder so they rotate having a difference in peripheral speed between them, and wherein the peripheral speed of the form dampening roller is made variable as desired to make the slip ratio between it and the plate cylinder in their mutual area of contact variable as desired. To this end, the form dampening roller is geared to a vibrator roller, and independent of a main motor for rotationally driving the plate cylinder there is provided a further motor for rotationally driving the form dampening roller independently of the plate cylinder at a rate of rotation that is made arbitrarily variable.
