SPECIFICATION Stephen Hunter Diaz PLEATED HEAT-RECOVERABLE TAPE A transversely pleated, longitudinally heatshrinkable tape is made from a heat-shrinkable polymeric film. One side of the tape may be adhesive-coated, and the other side may be coated with a thermochromic paint. The tape is wrapped around a substrate, and is particularly adapted, by reason of the pleats, to be wrapped around a substrate of non-uniform cross-section, e.g. a splice in a telephone cable. On heating the tape to its recovery temperature, the pleats disappear and the tape shrinks longitudinally to tightly cover the substrate. The tape may additionally comprise integral heating means.

METHOD OF MAKING A REINFORCED WELD

A method of joining abutting surfaces of polymeric material includes disposing between the surfaces insert means formed of thermoplastic material having dispersed therein a heat-activatable cross-linking agent. Reinforcement in the form of a foraminous member is positioned along the line of the join. The resulting assembly is heated under compression to cause the insert means to flow and the cross-linking agent to be activated. As a result, the insert means becomes bonded to the surfaces of the polymeric material and to the reinforcement means. One article produced by this method is in the form of a sleeve, the line of the join being substantially parallel to the longitudinal axis of the sleeve. The join is continuous from one end of the sleeve to the other and is of essentially the same thickness as the walls of the sleeve.

ABSTRACT OF DISCLOSURE The present invention relates to the fabrication of boat hulls and other three-dimensional objects of thermoplastic sheet material. The process comprises heating a sheet of the material along a predetermined pattern of lines to a temperature at which the material is softened, placing the sheet in a jig with the material of the sheet still soft along the heated liens and folding it along the softened lines, and retaining the sheet in its folded state in the jig until the material along the said lines is cool and stiffens. The preferred thermoplastic material is polypropylene, and by reversely folding the sheet along selected fold lines and integral hinge can be induced. In making a foldable boat, the pattern of fold lines is such that the sheet in its folded state has the shape of the hull of a boat. A blank when so prepared can be rolled into extremely compact form for transportation and to erect the hull is merely unrolled and with a little manual assistance put into the required shape and secured. Gunwales, one or more stiffening members and one or more seats can readily be affixed.

Method and device for sectionally sheathing objects with plastic

The invention relates to a method for sectionally sheathing objects with plastic, which is distinguished by the fact that a crosslinked tube produced from a shrinkable plastics material is stretched axially or radially under the effect of heat. Subsequently, this tube is cut axially for the formation of a shrinkable band. A predetermined length of this shrinkable plastics band (6) is laid around an object (18) over a predetermined section and held in a position sheathing the object. By supplying heat, the shrinkable band laid around the object is shrunk closely around the object to be sheathed, and the end sections of the shrunk band which are brought into contact against each other are bonded to each other under the effect of pressure and heat. Furthermore, the invention comprises a device for sectionally sheathing objects with plastic, which comprises: a means for wrapping around a shrinkable band (6), around a section of the object (18) to be sheathed, a means (11, 12) for holding the end sections of the band laid around the object, a means for pressing together the end sections of the band, a means for severing the ends of the band section as well as a means (19) for heating the shrinkable band to the shrinking temperature. <IMAGE>
