Patent number: 5333438Abstract: An improved power strapping machine comprising a strapping device and a soft touch package compression device. The strapping device includes plurality of coils for supplying strapping to a guide apparatus. A chute apparatus for routing strapping around an article or package to be strapped is connected to the guide apparatus. The machine includes sensors and a control circuit adapted to operate the machine continuously without the need to stop production, since when one coil is out of strapping or a misfeed occurs, the machine will automatically load another coil of strapping and continue strapping packages. The soft touch package compression device uses pneumatic-drive chain drive systems for moving soft belts up and down. The soft belts compress the package so that the strapping device can place a tight strap around the package.Type: GrantFiled: November 6, 1992Date of Patent: August 2, 1994Assignee: Signode CorporationInventors: Ronald W. Gurak, Allan J. Bobren, Frank A. Clochon, Janusz Figiel, Kenneth W. Lesner, Timothy B. Pearson, Kendall K. Raczek, Mark B. Renz, Allen D. Sordyl

Patent number: 5238521Abstract: A movable strap-engaging member is provided for being connected at a first pivot axis to a vibrator arm for accommodating pivot movement of the vibrator arm about the pivot axis while the movable strap-engaging member is pressing a first length of flexible thermoplastic strap against a second length such strap in an elongate strap-receiving path. The movable strap-engaging member is reciprocated generally transversely of the path to effect a friction-fusion weld of the strap lengths. The movable strap-engaging member has a configuration in which first and second centers of mass are spaced apart on a line that passes through the pivot axis and that is oriented generally perpendicular to the path. The product of the square of the distance along the line between the pivot axis and the mass of the first center of mass is substantially equal to the product of the square of the distance along the line between the pivot axis and the mass of the second center of mass.Type: GrantFiled: October 30, 1991Date of Patent: August 24, 1993Assignee: Signode CorporationInventors: Nelson Cheung, Janusz Figiel

Patent number: 5133532Abstract: A method and apparatus for tensioning a strap loop around an object and terminating the tensioning of the strap loop at a predetermined loop tension. The object is encircled with a loop of strapping having a predetermined thickness, width, and coefficient of friction. A leading end portion of the strap is restrained while disposing a trailing end portion of the strap adjacent a traction wheel that is rotatable about a first axis at a predetermined maximum available torque. A pressing member that is pivotable about a second axis oriented parallel to the first axis and that has a predetermined configuration and coefficient of friction is biased toward the traction wheel so as to press the strap trailing end portion against the traction wheel.Type: GrantFiled: October 11, 1990Date of Patent: July 28, 1992Assignee: Illinois Tool Works Inc.Inventors: Janusz Figiel, Peter Drabarek
