    摘要： A method and apparatus for grasping and advancing adjacent layers of thermoplastic film through the side sealing mechanism of a packaging machine includes a plurality of belts which travel about two sets of cooperating pulleys. Each pulley has two circumferential belt grooves defined within it, each belt groove being functionally adapted to allow the travel of a belt along it. A first line of travel is defined along a path which is parallel with the line of travel for articles moving along the wrapping machine. The second line of travel diverges away at a slight angle. The belts are truncated V-belts, the “truncated V” portion of the belts being disposed outwardly of the pulleys. Each set of pulleys is offset such that the belts cooperate in tooth-meshing fashion. A tail pulley of each set is mounted in an offset cam fashion and is spring loaded to apply tension to the belts. Disposed between the belt paths is a hot wire assembly having a similarly longitudinally diverging hot wire. The hot wire assembly utilizes one mounting block which is stationary and another which is rotatable. The mounting blocks are provided with means for allowing insertion of hot wire end connectors at a predetermined depth. An end sealing apparatus includes means for adjusting the end seal location relative to the vertical height of the article to be wrapped.

    摘要： A device for conveying packages includes a conveyor with a running surface ending with a terminal area, a series of stationary stops and vertical prongs under the stops and above the running surface. The prongs move along a path which follows a circular trajectory in the terminal area. Packages are introduced between two heat-sealing vertical belts in an inlet area. The inlet area of the vertical belts is situated at a distance from the terminal area of the conveyor. A forwarding belt, coplanar with the running surface of the conveyor, is situated between the inlet area and the terminal area of the conveyor. The forwarding belt is operated with a speed higher than the operation speed of the conveyor, so that the packages are not subjected to the prongs action when they rotate upward in the terminal area. The forwarding belt extends from the terminal area of the conveyor, to at least the inlet area of the vertical belts, and the stops protrude to cover the major part of the forwarding belt.

    摘要： The total heating energy to be given to the folded parts of packages (i.e. box-like items) is changed within a short period of time in response to a variation of transferring speed of the box-like items. As the heater moving mechanisms are operated, each of the heater blocks is moved towards or away from the inside parts of each of the package conveying annular belts in synchronization with the transferring speed of the box-like items. The number of heated blocks abutting against the inside parts of each of the annular belts is varied in response to the transferring speed of the box-like items.

    摘要： A machine for sealing polyethylene bags or the like of the type having conveyer bands for gripping and transporting the bags to be sealed at a constant velocity from the machine's inlet end, through a heating station, then through a cooling station to the machine's outlet end. The conveyer bands are formed from a material having good release (non-stick) characteristics with respect to the fused thermoplastic. Disposed at the heating and cooling stations, respectively, are heating and chilling bars (heat transfer bars), each being disposed in pairs on opposite sides on and in proximity to the conveyer bands. Means are provided for cyclically opening and closing both pairs of bars relative to the conveyer bands and for translating the bars longitudinally in reciprocating fashion with respect to the moving bands. As bags to be sealed are carried along by the conveyor bands, the heat transfer bars pinch closed on the traveling bands, but since the bars at this time are being translated in the same direction of travel (forward stroke) and at the same velocity as the bands, no band wear occurs. Toward the end of this forward stroke, the heat transfer bars open relative to the bands and the return stroke occurs with substantially zero force between the moving bands and the heat transfer bars. During the return stroke, the bars act as a preheat device to warm up the film prior to the forward stroke to obtain greater speed. Because the bars are of a predetermined greater length than the length of the reciprocating stroke, a continuous package seal is ensured.

    摘要翻译： 一种用于密封聚乙烯袋等的机器，其具有输送带，用于以恒定的速度从机器的入口端，通过加热站，然后通过冷却站到机器的出口端夹持和运输待密封的袋。 输送带由相对于熔融热塑性材料具有良好剥离（不粘）特性的材料形成。 分别在加热和冷却站处设置加热和冷却棒（传热棒），每个在输送带上和其附近成对设置。 提供了用于相对于传送带循环地打开和关闭两对杆的装置，并且用于相对于移动带以往复方式纵向平移杆。 当被密封的袋子被输送带带走时，传热棒在行进带上夹紧，但是由于此时的条杆在相同的行进方向（向前行程）上以相同的速度平移 乐队，没有乐队磨损发生。 在该向前行程结束之后，传热杆相对于带打开，返回行程在移动带和传热杆之间以大体上为零的力发生。 在返回行程期间，杆作为预热装置，以在向前冲程之前预热膜以获得更大的速度。 由于杆的长度大于往复冲程的长度，所以确保连续的包装密封。

    摘要： A machine for applying lids to containers and for further heat sealing a metal foil membrane to each container beneath its lid includes a main conveyor and a timing screw at the feed end of the conveyor for releasing open top containers onto the conveyor at equally spaced intervals. As the containers move along the main conveyor, captivator blocks, which are carried on synchronized chains located at each side of the main conveyor, converge toward and close upon the side walls of the containers so as to confine the containers in the horizontal direction while they move along the main conveyor. Lids are applied to the containers at a lid applicator while the containers are gripped by the captivator blocks. Thereafter the containers pass beneath an overhead belt and the lower pass of this belt is backed by a pair of skid plates and a plurality of rollers, with the rollers being interposed between the two skid plates. An induction coil creates a magnetic field beneath the rollers, and this field is of sufficient intensity to elevate the temperature of each foil membrane to above the point at which the membrane will bond to the rim of its container. As each container passes beneath the first skid plate, the force applied to the lid squeezes the membrane against the container rim with a constant force and excludes foreign particles from the interface. Thereafter the membrane is heated and as it is heated, the rollers apply an undulating force to the membrane, causing the heated membrane to seal snugly against the rim of the container. Finally the second skid plate applies a constant force to the membrane and holds it down against the container rim, allowing the membrane to bond to the rim as the membrane cools.
