Apparatus for forming and stacking sections severed from a web of tubular film

摘要

In an apparatus for stacking sections separated from an intermittently fed web of sheet material, successive sections are held by clamping means and transferred to the upper arm of a first suction belt conveyor having suction holes which are at a spacing larger than the length of each section and attract the trailing end thereof. A second suction belt conveyor with suction holes at the same spacing overlaps the first conveyor and takes over the sections with its lower run by attracting the leading ends. An intermittently operatively stacking conveyor under the second belt conveyor has the sections deposited thereon by means for withdrawing the sections from the second belt conveyor.
