Abstract
A mechanism for forming seals at spaced points along the length of a body of web material moved through the mechanism is comprised of two sealing jaws and a simple device for opening and closing the jaws whereby the mechanism consists of a small number of parts and may be made at a relatively low cost and to have a relatively light weight. The jaws are slidably supported relative to a base for pure linear motion and are moved between their open and closed conditions by an air cylinder or other fluid actuator which is unfixed to and floats relative to the base.
