US 3759169 A
Abstract
This machine straps a package with heat sealable plastic strapping. The strap is fed by geared feed and tension wheels around a yoke and against a stop. The strap is gripped against a side-retractable anvil on opposite sides of a vertically moving platen and knife assembly, while straddling a retractable tongue. A heated blade replaces the tongue whereupon the platen squeezes the heated joint and cuts the strap. The anvil and tongue are withdrawn for removal of the strapped package. The platen, tongue, anvil and sealing blade are controlled by a set of cams on a linear actuator.
