Abstract: The band delivery apparatus has two separate band stores, namely a band forward store (10.1) and a band return store (10.2). The two stores are constructed as chambers, which is controllable manner can receive a predetermined band material quantity. The filling and emptying of the stores is brought about by a coordinated cooperation of a buffer store separator (3) and the conveyor rollers (17.1, 17.2). The buffer separator (3) blocks the band passage upstream of the supply/exit openings of the two band stores (20.1, 20.2) and consequently leads to a bulging of the band in the storage areas. The filling of at least the band forward store is preferably assisted by a delivery means (11). The necessary band material quantity during prestorage can be precisely determined by means of sensors.

Abstract: A package strapping machine draws a thermoplastic strap off of a reel, loops the strap around a package, clamps a leading end of the strap, and then tightens the strap around the package with a strap tightening mechanism. A trailing end of the strap is cut underneath the leading end, and then both these ends are automatically welded together. When the strap is tightened, a portion of the strap is fed back towards the reel. The reel is provided with a device for rewinding this portion of the strap. A spiral spring stores energy from the rotation of the reel when the strap is drawn off, and when the strap is fed back the spiral spring causes the reel to rotate so as to rewind the strap. Because the strap is fed back towards the reel faster than the reel can rewind the strap, a loose strap portion accumulates between the reel and the strap tightening mechanism.

Abstract: A package strapping machine is capable of strapping a package with an adjusted, gentle force by welding ends of a thermoplastic strap. The machine is provided with a strap-elevating member in proximity to a strap-receiving element mounted on a pivotal member. Overlapping ends of a thermoplastic strap are looped around the strap-receiving element and the package, and are then welded under the strap-receiving element. The strap-receiving element is then withdrawn from between an under surface of the package and the welded portion of the strap. The strap-elevating member elevates the welded portion of the strap, slackened due to gentle tightening, from a point below to a point above the height of the strap-receiving element, with the result that the slackened, welded portion of the strap is held above the strap-receiving element as it returns to its original position. The strap thus does not impede the movement of the strap-receiving element.

Abstract: The present invention relates to a package strapping machine suitable for tying a package or bundle into a circular shape. A concave base supports the package in the circular shape. A synthetic resin tape is looped around the package and the base, and a leading end of the tape is held against a lower surface of the base by a clamping mechanism. The tape is then tightened, and the leading end of the tape is clamped together with a trailing end of the tape. These tape portions are then heated and pressed to weld them together, and thus the packae is tied in a circular shape. The concave base is then pivoted out from between the package and the tape. As the base pivots, stoppers adjacent the base contact portions of the tape to hold the tape and package in place and allow the base to be removed.

Abstract: An automatic binding apparatus produces a loop of tape and tightens the tape around an object that is inserted through the loop of tape. The apparatus has a bed-plate and a guide member which is swivelable into position on and off the bed-plate. Initially, the tape is guided through the guide member to form a small loop of tape. Thereafter the guide member is retracted and the loop of tape is enlarged by feeding more tape to the loop to accommodate large objects. Insertion of the object through the loop actuates a work detection switch and detection of the object produces an output signal which triggers a process whereby the tape is tightly bound around the object, is cut from the tape supply, and the ends of the tape are overlapped and pressure welded to one another. Removal of the bound object changes the state of the work detection switch and results in the repositioning of the guide member over the bed-plate and in the formation of a fresh loop of tape for a next object to be bound.
