Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a winding paper one-punch peeling apparatus for automatically cutting and peeling a one-piece covering the outer surface of a newspaper roll.

(Prior Art) In general, newspaper webbing used in a rotary press has a wrap (lower grade paper) on its outer peripheral surface in order to prevent loosening of the webbing during transport or damage to the surface. In addition, the end faces are covered and protected by paper end plates.

On the other hand, in a rotary press, when there is no web that is attached to the web feed reel and is fed to the web press at a constant speed, a new web that has the end of this web attached to the same web feed lead is used. Continuously feeding paper to the rotary printing press is performed by automatically adhering to the starting end of the paper.

Thus, when mounting the roll of paper taken out from the paper storage in the printing factory on the roll of paper for feeding to the rotary press, the start end of the roll of paper must be pre-processed for splicing after cutting and peeling the wamp. I won't.

By the way, conventionally, the cutting and peeling of the webbing tape have been performed manually. That is, in the vicinity of the end of the web, a bamboo spatula is inserted between the web and the wand, and this is moved in the axial direction of the web to cut the wamp in the longitudinal direction and then peeled off. Incidentally, the end plate has already been removed when the one-piece is cut and peeled.

However, the manual cutting and peeling of the wamp has a problem that the work efficiency is poor and the labor cost rises.

In addition, since the bamboo blade is moved by hand when cutting the wamp, there is a problem that the outer peripheral surface of the paper roll is easily damaged and the paper loss increases.

Further, when peeling the cut wamp, the paper roll is heavy, which is extremely hard work.

However, since the peeled wamp becomes bulky or becomes messy, there is a problem that the post-treatment of the wamp cannot be performed satisfactorily and easily.
