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.

Dual coil power strapping machine

Apparatus and method for securing a thermoplastic strap around a package by compressing the overlapping strap end portions together and moving one of the overlapping end portions in a transverse direction relative to the other at a very high frequency and small amplitude to melt and fuse the interface region therebetween. The transducer used to produce the ultrasonic vibrations is supported solely at its nodal point where it is vibration free.

Ultrasonic friction-fusion method and apparatus

A chain strap wrapping and guide assembly including a plurality of crown-shaped rollers that are guided by V-shaped guides. The chain is driven by a motor operated sprocket.

Resilient chain strap wrapping and tensioning device

An apparatus and method are disclosed for forming a loop of flexible binding about objects positioned seriatim in an object receiving station. The apparatus includes a chain loop driven around the object receiving station. While a previously bound first object is in the receiving station, the chain is driven in one direction to move carrier rollers on the chain so as to pull the trailing portion of a binding through a major portion of the locus of a closed path around the receiving station while the lead end of the binding is held adjacent the receiving station. Spaced portions of the binding are guided from the interior of the path around the receiving station to maintain the binding in the configuration spaced outwardly of the receiving station. Subsequently, the first bound object is removed from the receiving station and a second object is positioned therein. The guiding of the interior of the binding around the receiving station is terminated so as to permit the binding to contact the second object while further pulling the trailing portion of the binding to complete the closed path and then form a tensioned loop about the second object.
