SYSTEM AND METHOD FOR CUTTING TUBULAR SHRINK SLEEVE MATERIAL FOR APPLICATION TO CONTAINERS

摘要

A tubular film cutting arrangement for cutting tubular shrink film into sleeves of suitable length for application to containers includes a support member having a film passage opening therein; a plurality of knife drive pulleys rotatably mounted to the support member and spaced apart around the film passage opening, each knife drive pulley having a knife member mounted thereon for rotation with the knife drive pulley; a plurality of idler rollers rotatably mounted to the support member, each idler roller arranged between two of the knife drive pulleys, wherein a drive belt path is formed between the knife drive pulleys and the idler rollers; and a drive belt extending along the drive belt path such that a first side of the drive belt is in contact with each of the knife drive pulleys and a second side of the drive belt is in contact with each of the idler rollers; wherein the idler rollers are positioned to interact with the second side of the drive belt in order to hold the first side of the drive belt in contact with the knife drive pulleys.
