초록 ▼

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.

대표청구항 ▼

A method for production of bags from thermoplastic film in the form of a continuous longitudinally advanced web having at least two layers with the film layers continuously joined along one longitudinal edge of the web wherein said web has a cross-section such that the number of film layers in one portion is greater than in the thickness of the remainder of said cross-section, from the leading end of which web bags are successively made by transverse seam welding and severance carried out at substantially equally spaced locations on the web, the steps comprising: feeding said web tangentially onto the outer surface of a continuously rotating welding drum provided with a plurality of welding anvils extending parallel to the rotational axis of said drum and spaced equally about its circumference; effecting a preliminary seal of the film layers during a predetermined length of said travel of said web on said drum along a portion of a path transverse to the direction of travel of the web, wherein said web has a cross-section such that the number of film layers in said portion of said transverse path is greater than in the thickness of the remainder of said cross-section; and thereafter simultaneously welding and severing said web along the whole of said transverse path inclusive of said preliminary seal.
