Patent number: 4903559Abstract: A process and apparatus for making a repetitive arc cut in a continuous manner in a continuous supply of sheeting possessing edges, which involves providing a moving sheeting across a cutting area and passing through the area an arc-directed omnidirectional cutting means at and across an edge, in the general direction of the sheeting, to puncture a portion of the moving sheeting, maintaining the arc directed velocity of the omnidirectional cutting device at a rate greater than that of the directional velocity of the sheeting such that the puncture is enlarged to a lineal cut. The most favorable application of the invention involves the use of waterjet cutting to cut holes, especially primarily round holes, in multi-wall plastic constructions.Type: GrantFiled: September 22, 1987Date of Patent: February 27, 1990Assignee: First Brands CorporationInventor: Harry A.

Patent number: 4867735Abstract: A method and apparatus are provided for continuous fabrication of bags from a longitudinally advanced multi-layer thermoplastic film web fed tangentially onto a rotating drum for carrying out transverse web seam welding and severing, the principal novel feature being provision of preliminary heating carried out across at least part of the width of web at which the final seam and sever is to take place. The preliminary heating step is advantageous where the thickness of film layers to be sealed and severed is not uniform across the width of the web or in which the uniform thickness of the film layers is such that seaming and severing in a single step requires an undesirably long time for continuous high speed production. The method can be adapted for production of bags of different widths.Type: GrantFiled: October 1, 1987Date of Patent: September 19, 1989Assignee: First Brands CorporationInventor: Donald E. Wogelius
