Assignee:

Signode Corporation - Glenview IL

US Classification:

US Patent:

40010643, Jan 4, 1977

Filed:

Sep 3, 1975

Appl. No.:

5/609361

Inventors:

Robert J. Nix - Park Ridge IL

Assignee:

Signode Corporation - Glenview IL

International Classification:

B32B 3118
B32B 3120

US Classification:

156 736

Abstract:

A manual strapping tool for joining overlapping portions of a thermoplastic strap includes a cantilevered spring having fixed and vibratory ends. The fixed end is rigidly anchored to a base member and the vibratory end supports one of a pair of jaws having opposing strap gripping surfaces. The other jaw is fixedly positioned on the base so that the strap gripping surfaces are normally in confronting engagement. An operating handle is pivotally mounted on the base member and swingable from a start position through a strap compressing position and a strap sealing position. In the start position, a lifter cam on the operating handle engages a lift arm causing the arm to raise the vibratory end of the cantilevered spring and to separate the strap gripping surfaces so that overlapping strap portions can be inserted therebetween. As the operating handle is swung from the start position to the strap compressing position, the lifter cam is disengaged from the lift arm releasing the vibratory end to compress the overlapping strap portions between the strap gripping surfaces. Further movement of the operating handle into the strap sealing position causes a triggering cam means on the operating handle to deflect and release the vibratory end so as to effect relative sliding frictional movement between the compressed overlapping strap portions and to melt the interface regions thereof.

International Classification:

B32B 3100

US Classification:

156361

Abstract:

A tool is provided for constricting a loop of thermoplastic strap that encircles an article and has overlapping strap segments and for sealing the segments with a friction fusion weld. A multiple drive shaft assembly is driven by a motor which can be rotated in a first direction and then in a second, opposite direction. The drive shaft assembly is engaged to a tension wheel in the first direction of rotation to constrict and tension the loop. A sensing and control means senses a predetermined loop tension level and reverses rotation of one of the drive shafts to the second direction. A mechanism responsive to the rotation of the shaft in the second direction is provided for pressing the overlapping strap segments together and for moving one of the segments relative to the other segment to effect the friction fusion weld.
