摘要:
There is disclosed a method of conveying and heat-treating an extrudate, which method comprises: introducing the extrudate to be conveyed and heat-treated onto a cushion of gas which gas is at or above a predetermined temperature; causing the extrudate to be conveyed on the cushion of gas; and removing the conveyed and heat-treated article from the cushion of gas. Also disclosed is an apparatus for manufacturing a heat-treated extrudate comprising:
(i) an extruder which includes an outlet from which the untreated extrudate is extruded; and (ii) conveying and heat-treating means for conveying and heating the untreated extrudate, said conveying and heating means comprising: an elongate conveyor means (1) communicating with the outlet of the extruder and including, along at least a portion of its length, a plurality of spaced-apart outlets (10, 11) through which a gas at or above a predetermined temperature is passed under pressure thereby to create a cushion of moving gas to convey and heat-treat the extrudate.

There is disclosed an elongate blank (2), intended to be formed into an elongate channel-shaped core for a strip structure, the blank comprising a plurality of regularly spaced pairs of legs (6A, 6B) and a central region (10), each leg (6A, 6B) of a pair extending from a position outwardly of the central region (10) of the blank to a lateral edge (18A, 18B) of the blank, the legs of a respective pair being substantially collinear, and the central region (10) being provided with a plurality of evenly spaced apertures (22), each of which is collinear with the centreline of a respective pair of legs (6A, 6B) of the blank. A method of producing the elongate blank is also disclosed as well as a flexible channel-shaped strip structure incorporating a channel-shaped core made from the elongate blank.
摘要:
There is disclosed an elongate strip (3) including a channel for receiving a sheet of glazing material (6) or other element, the channel having a wall (17) made resistant to deformation at a free end region (20) thereof by the presence of a longitudinal resilient insert (24). The elongate strip is suitable for use around vehicle door openings to provide a semi-flush glass sealing arrangement. The presence of the resilient insert obviates the need for a central metallic core extending across the whole width of the strip.
摘要:
There is disclosed an elongate finishing strip (20) comprising a channel-shaped portion having a base and two side walls (9A, 9B), the remote end (10A) of one of the side walls (9A) being enclosed by a decorative element (2) having an enlarged end region (11) which is partially secured in a recess (12) provided in the one side wall (9A) and opening towards the outside of the one side wall (9A) in the remote end region (10A) thereof, said decorative element (2) extending from its enlarged end region (11) around the remote end (10A) of the said one side wall (9A) and returning in abutment with the inside of the said one side wall (10A), wherein the mouth of the recess (12) is defined between opposed flexible regions (13′, 14′)which permit insertion of the enlarged (11) end of the decorative element (2) into the recess (12) and wherein a flexible limb (15) extends into the recess (12) towards the mouth thereof to abut the enlarged end (11) of the decorative element (2) and urge that element (2) against the relatively flexible regions (13′, 14′) at the mouth of the recess.

There is disclosed a strip structure (10) indented for clamping engagement on a flange or like member, the strip structure (10) having a channel defined by a base (12) and two opposed side walls (13, 14), each side wall being provided with an elongate Iimb (16, 17) directed inwardly and towards the base (12) such that the limbs (16, 17) abut at their free end regions (20, 21); wherein that face of each limb (16, 17) which faces the corresponding face of the other limb (16, 17) is straight or substantially straight over a portion of the limb in the region of the free end (20, 21); wherein the side walls (13,14) are also each provided with an inward projection (26, 27) nearer the base (12) of the channel than the root of the limb (16, 17); and wherein each of the limbs (16, 17) is provided on that face which faces the side wall (13, 14) with a recess (22, 23) in which the projection may be accommodated; the arrangement being such that, in use, when the strip structure (10) is being clamped on a flange or like member, the flange causes the limbs (16, 17) to be moved apart, with the projections (26, 27) being accommodated in the corresponding recess (22, 23), whereby the clamping may be effected without undue force, but, when an attempt is made to remove the strip structure (10) from the flange, the free end regions (20, 21) of the limbs (16, 17) grip the flange and the limbs (16,
