    摘要： An electrical heating element, in particular for a hot-wedge film welding device, having two electrodes and a heating resistor arranged between the electrodes such that an application of an electrical voltage to the electrodes results in heat being produced along the length of the heating resistor. The heating resistor is designed to correspond to the shape of a heating wedge of a film welding machine, such that it can replace the heating cartridge and the hot wedge of a conventional film welding device. It is preferably produced from a conductive ceramic material and is distinguished by uniform heat distribution, good thermal conductivity and resistance to wear, as well as by excellent corrosion resistance.

    摘要： An improved apparatus and method for joining two or more thin sheets of thermoplastic materials along a welded seam includes a welding assembly and a means for feeding the thermoplastic sheets to the working area of the welding assembly. The welding assembly includes a heated platen welding press coupled with a welding tool, an energy generator electrically connected to the welding tool and control means electrically connected to the welding press, the welding tool and the energy generator. The welding press includes a pair of opposed platens, means for heating each of the platens and pressing means for displacing at least one of the opposed platens in the thickness direction of the thermoplastic sheets. Pressure is applied to the thermoplastic sheets by using the pressing means to displace at least one of the heated platens in the thickness direction of the thermoplastic sheets. Heat produced by the heating means is then transferred to the thermoplastic sheets by the heated platens to raise the temperature of the thermoplastic sheets in the area of the welded seam to a first predetermined temperature which is below the softening temperature of the thermoplastic materials. High frequency energy produced by the energy generator is then conducted to the thermoplastic sheets by the welding tool to raise the temperature of the thermoplastic sheets in the area of the welded seam to a second predetermined temperature which is above the softening temperature but below the melt point of the thermoplastic materials. Conduction of the high frequency energy is then discontinued so that the thermoplastic sheets fuse together along the welded seam under applied pressure. Application of the pressure is then discontinued so that the welded thermoplastic sheets may be removed from the welding assembly.

    摘要： An apparatus for use in sealing layers of thermoplastic material together from one side of the layers includes a heat sealing electrode having a first conductive element mounted on a support and adapted to be connected to a source of high frequency energy, and a second conductive element mounted on the same support but in spaced general parallel relation to the first conductive element and adapted to be connected to an electrical ground. The conductive elements are electrically insulated from each other and, when they are applied to one side of the thermoplastic sheet material to be sealed and high frequency energy is supplied to the first electrode, a seal is formed in the material beneath and between the ends of the electrode elements.
