Abstract: An infinite heat sealing assembly preferably for heat sealing a thermoplastic heat-shrinkable plastic film, has a heat sealing assembly for cutting and sealing a seam in a film or layers of film without regard to the length of the seam. The heat sealing assembly includes a heated blade and a plurality of belt conveyors for conveying the film with a desired tracking through the assembly. An adjustable angle blade and slotted film support ramp result in improved sealing of heavier gauge films by increasing the dwell time of the film on the heated blade.

Abstract: Chains of coherent labels for use on garments are obtained by severing a running web of woven or knit textile material with heated wires so that the web yields two or more elongated strips having a width exceeding the width of a label. The strips are advanced under tension, and their marginal portions are folded over the adjacent zones of central portions of the respective strips. The thus folded marginal portions are thereupon bonded (particularly heat-sealed) to the respective central portions. The combined width of two marginal portions matches the difference between the width of a strip and the width of a label. Each strip consists of a series of neighboring labels.

Abstract: Slit-sealing apparatus for high density plastic sheets is disclosed. The sheets to be slit-sealed are passed over rollers, at least one of the rollers having a brake so that the plastic is put in tension. A curved tensioning bar is urged against the sheets to deflect the sheets and increase the tension, tension being greater in the area to be slit. Slitting is accomplished by an elongate knife blade angularly disposed with respect to the web of material so that the material is slit, then the material drags along the sides of the knife blade. The knife is heated to seal the edges, and the slit edges are held in tension until they reach the next roll. The sealed edges are then heated for final setting to achieve a strong seal.

Abstract: A method is provided for the pretreatment of superposed layers of thermosplastic film which are to be heat sealed together, longitudinally, along a predetermined area. The film layers to be heat sealed are preheated utilizing heated air along a defined, continuous longitudinally extending area of the film layers. The preheated area is subsequently passed through a slit-seal device which simultaneously severs the preheated film layers and seals the severed edges together. The method is particularly useful for the slit-sealing of a continuously advancing flattened tube of thermoplastic which is characterized by having a non-uniform gauge in cross-section.

Abstract: In a resistance heating blade for simultaneously slitting and edge sealing a plastics web, the flat blade having a projection which, in operation, projects edgeways through the path of the web and serves to cut and seal together the film layers, the blade is shaped so that its smallest cross-section is located in advance of the apex of the projection, so that heat is concentrated at or about the point at which the blade first contacts the web.
