ABSTRACT:
An end-trimming apparatus for roll-like products. The apparatus trims both ends of a roll comprising a sheet-like material wound up on a core, particularly, stretchable one such as plastics film, by cutting off the irregularity of both the ends, finishing them into flat faces. It comprises a conveying means for carrying rolls horizontally to a given location, a supporting means of a pair of chucks for supporting the roll at both the ends, while providing it with a rotation in the winding direction of the roll, and a cutting means provided close to the pair of chucks, including a pair of disk cutters arranged co-axially and having respectively separate shafts parallel with the shafts of the chucks, the disk cutters being capable of moving toward and away from each other and of reciprocating in the direction at right angle to said toward-and-away motion. The pneumatic and electric control means control the co-operation of the above means to effect an automatic or semi-automatic trimming of the roll ends in an orderly sequence, providing a great improvement in labor saving and cost reduction.
