Title:
LASER CUTOFF STACKER ASSEMBLY
Document Type and Number:
WIPO Patent Application WO/2005/107997
Kind Code:
A1
Abstract:
The present invention contemplates a machine and method for performing the laser sealing and laser cutting of flexible material into segments, such as a polymeric web in which the segments will ultimately be individual bags. The machine includes a generally cylindrical drum (702) having openings on an exterior surface. A laser produces a laser beam that contacts the flexible material while the flexible material is being held on the drum (702). The drum (702) is comprised of drum sections (712) that can be independently moved in the radial direction. The machine includes a cam system causing the drum sections (712) to be sequentially moved in the radial direction. Typically, this radial movement is for the purpose of releasing the individual segments (780) of the flexible material that have been cut by the laser.
