Method and Apparatus for Heat Splicing Thermoplastic Film

摘要

A method and apparatus for continuously supplying thermoplastic webbing to an application apparatus is disclosed. In one aspect of the invention, first and second webs of thermoplastic material are held stationary and heat spliced together upstream in a line operation while a downstream segment of the thermoplastic webbing is continuously supplied to an application apparatus downstream in the operation. The heat splicing step is carried out by bringing together first and second opposable splicer clamps to form an overlapping area between the first and second webs and applying a heat impulse to the overlapping area to bond the webs together.
