Abstract
Apparatus for successively depositing sections severed from the leading end of a web of film on a support to form a stack in which the sections are staggered comprises an output shaft carrying two suction tubes or suction tube rows which engage a respective section and transfer it to the support as the output shaft is turned intermittently by interconnected crank arms from an input shaft which is horizontally offset from the output shaft and parallel thereto. The tubes or rows of tubes include an obtuse angle and are alternately revolved by the output shaft through the obtuse angle and the explement thereof.
Claims5
Apparatus for transferring severed sections from a transverse welding and transverse severing means to a support, said apparatus comprising:
- first and second suction tube means having outer ends for suction attracting a severed section;
- a shaft supporting inner ends of said suction tube means so that outer ends of said first and said second suction tube means are spaced from each other by an obtuse angle (.alpha.) slightly less than 180.degree.;
- means for rotating said shaft so that said first and said second suction tube means are alternately moved between a vertically extending orientation for engaging a section to be transferred and a deposit position for depositing a transferred section on the support, said means for rotating alternately rotating said shaft through the obtuse angle (.alpha.) and the explement (.beta.) thereof.
