First Claim
Patent Images
1. A machine for applying tubular film to products, the machine including:
- a mandrel assembly about which tubular film is passed as the tubular film is fed downward over the mandrel assembly;
a film cutter positioned along the mandrel assembly for cutting the tubular film into sleeves sized for application to containers passing below the mandrel assembly, the mandrel assembly including a sleeve section located below the film cutter and about which a sleeve length portion of the tubular film extends prior to each cutting operation of the film cutter to produce a cut sleeve;
a sleeve ejection arrangement including a rotatable ejector wheel disposed along the sleeve section of the mandrel assembly so as to be positioned along each sleeve length portion of the tubular film prior to each film cutting operation,wherein the rotatable ejector wheel is rotated continuously during repeated feeding and cutting of the tubular film to produce multiple cut sleeves that are sequentially ejected from the mandrel assembly.
