    摘要： For heat-setting tubular articles (such as can bodies) of an at least partly biaxially oriented crystallisable polymer, preferably a saturated linear polyester such as polyethylene terephthalate, e.g. for thermally processable food containers, a tube (26) of the polymer is fitted over a mandrel (101) and clamped at its ends to the mandrel at a temperature belowthe glass transition temperature of the polymer. The tube is then heated, e.g. by inserting a heater (28) into the interior of the mandrel, above the temperature to which it is to be heat-set (at least 60°C above for PET) whereupon it shrinks into contact with the mandrel but is restrained from axial or further radial shrinkage. The tube and mandrel are cooled to below the heat-set temperature and the tube may then be cut by knives engaging in circumferential grooves (22) into can body sections. Contact between the tube and mandrel is released, e.g. forforcing compressed air out through small holes (16) in the mandrel surface to allow the tube and mandrel to be separated.Tubularbodies with one closed end can be heat-set on a mandrel with a correspondingly shaped end.

    摘要： A wraparound recoverable sleeve (1) for encapsulating cable splices has a flap (7) which underlies opposing edges (4) to provide a seal between them. The flap has recoverable longi- tudinai corrugations (8) which reduce the tendency of edges of the flap to dig into the overlying sleeve as the sleeve recovers. The lateral flexibility of the flap (7) is increased by the corrugations (81, and longitudinal bending is resisted until the corrugations (8) have recovered away and the material of the flap (7) softened. The corrugations (8) may be filled with a sealing material.

    摘要： A cable breakout article (78) which is formed of a polymeric material and which is preferably heat-recoverable comprises a body portion and at least two tubes or outlet portions (91 to 94) leading from apertures in the body portion. The length and flexibility of the tubes (91 to 94) is such that at least one of them can be bent away from the other(s) to allow operations such as heat recovery to be carried out on an end portion of one of the tubes in isolation from the others. Preferably one or more of the tubes (95) is corrugated at least near its end adjacent to the body portion (78) so as to assist bending.
