Abstract: In a package strapping machine, a plate type pivotal member is adapted to turn pivotally on a main shaft held on the base plate of the machine in parallel with the direction in which a strap is forwarded. Two clamps and a pressing device are mounted on a surface of the pivotal member and adapted to move up and down so as to be adapted to press the strap against the under surface of a lateral projection provided on the upper free end of the pivotal member. In cooperation with a sidepiece secured to the under surface of the top board of the machine, the pivotal member serves to prevent the strap from breadthwise deviation.

Abstract: A band type strapping machine comprises a swing lever, pivotally supporting a gripper for gripping a band, adapted to swing according to the rotation of a cam mounted on a cam shaft, a control bar engaged with the swing lever to follow the movement of the swing lever, a driving roller operating to engage with a band tightening roller, the driving roller being strongly brought into contact with the band tightening roller rotated at a low speed, high torque by actuation of a solenoid.

Abstract: Apparatus for tensioning a plastic strapping band positioned around a package and for connecting the overlapping ends of the band by hot bonding consisting of a fastening mechanism for hot bonding the overlapping ends of the band and including a backing plate, between the band and the package, against which three plungers aligned along the longitudinal axis of the band can be applied, the first plunger securing the free front end of the band, the second plunger securing the rear end of the band, and the third, middle, plunger forcing the overlapping ends of the band against a hot-bonding mechanism in the form of a heated cutter and compressing the molten ends together. The three plungers (27, 28, 29) aligned along the longitudinal axis of the band (20) are activated with a single cammed disk (31) on a shaft (67) perpendicular to the longitudinal axis of the band.

Abstract: A machine and method are disclosed for securing a loop of thermoplastic strap around an article so that two overlapping portions of strap are bonded together. One form of an apparatus in the machine has a strap engaging weld pad with spaced-apart, parallel strap-engaging ribs for effectively making a friction-fusion weld in thin film strap. Another form of the apparatus in the machine includes a rack gear associated with a weld pad and engaged with an arc of teeth on a torsion bar for utilizing the torsional oscillation kinetic energy to reciprocate the weld pad along a linear path of motion. Another form of the apparatus in the machine includes a strap carrier chain for forming the strap in a loop about an article and the chain may include a resilient lug positioned between each pair of adjacent cross pins in the chain.

Abstract: An apparatus for heat sealing together layers of strap of thermoplastics material, wherein at least one thin flat electrical heating element is supported under tension and between the layers of strap and the layers of strap are pressed together with a fusing pressure by at least one resilient pressure pad. The heating element, a support for the heating element and the resilient pressure pad form a heating and fusing assembly which is moved in unison relative to the layers of strap so that in use, the heating element moves between the two layers of strap generally in a longitudinal direction thereof.

Abstract: This invention discloses apparatus for binding an article, such as a pack of bank notes, with a tape in a binding position. For this purpose, with rotation of a rotating member, the tape is supported by tape loop supporting pins and is wound to form a loop before a binding operation. The article is pushed into the loop and pressed before the tape is wound around the article. The tape supporting pins are retracted to disengage from the loop. The tape is drawn in a direction opposite to the supplying direction so as to be wound tightly around the article, and the trailing end of the tape is cut. The cut end of the tape is adhered to an adjacent portion of the tape. In this manner, tape binding is completed.

Abstract: A method and apparatus are provided for forming a strap loop and securing it about an article. The strap free end is pressed against a guide surface and moved in a path to form a primary strap loop while permitting the primary strap loop to twist off of the guide surface. With the free end of the strap held against further movement, the trailing portion of the strap is fed to expand the loop to a predetermined larger size. The article is inserted in the loop and the trailing portion of the strap is withdrawn to tighten the loop about the package. The trailing portion of the strap is severed from the tightened strap loop and the overlapping portions of the strap are sealed by a friction-fusion weld.

Abstract: Machine for tying packages or the like in which the tying means which is held fast at one end is guided by means of a tying means guide device around the package in the manner that the tying means guide device which is driven cyclically back and forth, its forward movement, accumulates a layer of tying means which surrounds the package, which layer is wound around the package upon the following return run, and in which there is preferably provided, below the support table for the package, a sealing device which connects the ends of the tying means and cuts off one end, the sealing device having grippers associated with it for holding the tying means fast. Each one of the grippers together with the end of the tying means held fast by it, carries out in cyclic dependency, a rotary movement which turns the gripper slot around. One of the two grippers, respectively, which are additionally axially displaceable, in a crosswise rotary position of its gripping slot S, pushes the tying means from the sealing device.

Abstract: A method of and apparatus for packaging a stack of tiles of which the tiles are supported on one edge thereof, in which the stack is supported at its base from one side only of the longitudinal central line of the stack and at another location of the stack, whereby to permit wrapping and securing a strap around that section of the stack which is unsupported at its base to form a tile package.

Abstract: There is disclosed an apparatus for manufacturing angle-section members and binding these members in bundles, in which the angle-section members, formed at a manufacturing station drop, apex upwards, onto supports carried by a conveyor to form a nested stack of the angle-section members on each support. The stacks thus formed are conveyed, on their supports, under binding devices at a bending station where each binding device bends a fastening element about the stack to form a bound bundle. Each bending device comprises a vertically slidable slide element having a bifurcated lower end defined by two downwardly extending arms the lower ends of which have pulleys around which a chain passes to extend between the arms, and upwardly from the pulleys, on the outsides of the arms, the chain being kept resiliently under tension.

Abstract: A packaging machine of the type primarily designed to package objects normally having an outer curvilinear configuration within heat shrinkable material. A conveyor assembly is mounted on a housing and maintained in continuous motion along a predetermined path of travel whereby the conveyor assembly comprises a plurality of roller elements at least a portion of which are maintained in constant rotary motion so as to impart this rotary motion to the material and the objects being packaged. A plurality of heated cutting elements are disposed in adjustable, spaced apart position in substantially transverse relation to the path of travel and in interruptive, severing relation to the material at least partially encasing the objects being packaged. A heat tunnel is further provided to apply an additional heat environment to the severed packaging so as to conform the packaging essentially to the configuration of the object being packaged.
