Abstract
A manually operable combination strapping tool for applying plastic strapping around an object includes a strap-tensioning and gripping mechanism for holding the strap in a tensioned loop around the object with the supply portion of the strap overlapping the leading end thereof, and a heat-sealing mechanism which includes a movable pressure block and a heater movable to and from a heating position between the overlapping strap portions. As the heater is moved between the overlapping strap portions, the pressure block is moved to cooperate with an anvil to press together the heating element and strap portions for melting thereof. After retraction of the pressure block and the heater by separate bias means, the pressure block is moved for cooperation with the anvil to clamp therebetween and bond together the melted strap portions and sever the supply portion of the strap. Ridges on the pressure block cooperate with complementary grooves in the anvil to deform the overlapping strap portions during bonding thereof and form a corrugated joint therebetween. Means limiting the pressure with which the strap and the heater are pressed together and cooling means are also provided.
