Definitions

  • the object of the present invention is to simplify the arrangement of the wires employed in the formation of the folds in such a manner that the manufacture of the complete fabric producing machine is facilitated, its cost of production reduced and time of stoppages occasioned by damage to the wires greatly reduced.
  • any one of the wires of a plurality of wires forming the spaces into which the pile elements are pressed to form a fold is mounted upon a supporting member so as to be removable therefrom and a substitute replaceable therefor without of necessity disturbing any more than at the most the next adjacent wire.
  • Figure 1 illustrates in sectional elevation a be more particularly deto the accompanying drawmechanism constructed to form pile elements into folds and deliver the same in readiness to be adhesively secured to a backing;
  • Figure 2 illustrates on an enlarged scale folding mechanism operable to press pile elements into the spaces formed between a series of wires
  • Figure 3 illustrates on an enlarged scale to Figure 2 the formation of pile elements into a series of folds arranged sufficiently close to one another that the exposed ends of the folds form a substantially continuous surface;
  • Figure 4 illustrates on an enlarged scale a modified construction of part of the mechanism illustrated in Figure 1;
  • Figure 5 illustrates on an enlarged scale the manner in which a series of wires are secured into bundles with the wires maintained sufficiently close to one another that when, the pile elements 8 Claims; (Cl. 15471.1)
  • Figures 6 and '7 illustrate two constructions in accordance with the present invention, whereby in the case of Figure 6, any pair of the wires and in the case of Figure '7, any one of the wires of 'a plurality of wires forming the spaces into which the pile elements are pressed to form a fold, are mounted upon a supporting member so as to be removable therefrom and a substitute replaceable therefor without of necessity disturbing any more than at the most the next adjacent wire; and Figures 8 and 8 illustrate part sectional side and end elevations of a drum constructed so as to permit the surface thereof to be provided with milled grooves in which wires can be mounted in accordance with the present invention and particularly in the manner illustrated in Figure 6.
  • FIG. 1 and 2 there is illustrated in Figures 1 and 2, a mechanism which comprises a drum 1, which is cast so as to provide in the periphery thereof steam chambers 2 which extend around the drum.
  • the steam chambers 2 are connected to conduits 3 arranged in communication with a conduit 4 which communicates with a steam passage 5 formed axially in a shaft 6 rotatable in bearings 1 and 8.
  • the above construction permits steam to be admitted axially of a constant supply of steam fed to the steam chambers 2, the steam being exhausted through conduits 9 and 10 into a second axial-passage ll formed in the shaft 6.
  • l is, in accordance with the above construction, maintained at a desired temperature.
  • wires I2 there is mounted upon the surf-ace of the drum' l a series of wires I2, the construction of which will be more particularly described with reference to Figure 5.
  • the wires I2 are mounted on the drum I so that the wires are arranged sufficiently close to one another that when pile elements l3 (such as fibres in the form of a batt) are pressed into the spaces between adjacent wires l2 ( Figure 3) the exposed ends M of the folds are formed into a substantially continuous surface.
  • the pile elements it are pressed into the spaces formed between adjacent wires by a folding mechanism ( Figure 2) operable periodically to move reciprocal blades I5 and
  • the folds, formed between the adjacent wires l2. are moved forwardly as the drum l rotates, bringing the exposed ends It of the folds beneath a roller it ( Figure 1) operable to spread an adhesive, for example unvulcanised rubber, upon the exposed ends I4 of the said folds.
  • the drum thereafter carries the exposed ends M of the folds coated with adhesive to a backing and the backing andthe exposed ends of the folds are subjected to heat both internally through the drum and externally through steam heated plattens l so as to vulcanise the rubber solution and cause the backing to adhere to the exposed ends 14 of the folds. from the drum whereupon the folds of pile elements are drawn from the adjacent spaces between the wires so as to freethe wires and permit the same to rotate once again with a supply of pile elements beneath the folding mechanism illustrated in Figure 2, thereby providing a continuous method of manufacturing a pile fabric.
  • the wires are constructed in the manner illustrated in Figure 5, namely by a series for example 12 wires being mounted with spacing elements l8 disposed between adjacent wires and the whole drawn up by a screw l9 so as to form the wires into a fbundlei
  • Each bundle of wires extends across the full width of the drum, and each wire is approximately /40 of an inch thick and the distance between adjacent pairs of wires is little over 1' 6 of an inch.
  • the bundles of Wires are secured to the surface of the drum I byjmeans of bolts 29 (Figure'2) which extend through the periphery of the drum at those portions thereof where there is no steam chamber.
  • the bolts engage with a series of slots 2
  • Figure 6 illustrates a portion of the surface of a drum wherein the wires I 2 are of U-form and are mounted upon the surface of the drum by milling grooves into the surface thereof and thereaftercaulking the wires into the surface of the drum by means of, for example, copper caulking 22.
  • wires illustrated in Figure 6 are of U-formation, they could be constructedas independent wires.
  • the wires are mounted in asupporting member 23 ( Figure 7) which is of similar-cross-section to the lower portion of the bundle of wires illustrated in Figure 5.
  • the supporting member 23 comprises a singlepiece of material as distinct from the laminated construction of the lower portion of Figure 5.
  • the wires l2 are held in the sup.- porting member 23 by means of the caulking 22 in-a manner similar to that illustrated in Figure 6.
  • bunin Figure 7 will be atmeans of bolts extending dle of wires illustrated tached to the drum by through the drum in the same manner in which the bundles of wires illustratedin Figure 5 are, according to existing practice, attached to the drum; nevertheless a construction in accordance with the present invention presents the distinct advantage over the existing practice inasmuch as when it becomes necessary to replace a damaged wire it is not essential to remove the whole bundle, which includes the damaged wire; it sufiices to remove the caulking Which is holding the damaged wire in position an subs i u e a n w ir for the damaged one.
  • the drum I is then shrunk upon an inner drum 25 and bolts (not shown) are arranged to extend through the drum at points between the steam chambers 2 in the manner hereinbefore described with reference to Figures 1 and 2.

  • a drum comprising an unbroken surface with grooves provided therein, a series of wires mounted in said grooves and disposed parallel with the axis of said drum, packing material for detachably holding the said wires in the said grooves, and means for supplying steam to the unbroken interior surface of the said drum.
  • a drum comprising an unbroken cylindrical surface with U-shaped grooves provided therein, a series of wires of U-cross section mounted in said U-shaped grooves, said wires being disposed parallel with the axis of said drum, and packing material holding said wires in the said grooves and being removable therefrom to allow exchange of said wires individually and independently of each other.
  • a machine for manufacturing pile fabrics which comprises in combination, a rotatable body having grooves provided at the outer surface thereof and arranged parallel to the axis of rotation of said body, wires arranged in pairs, with each groove containing only one of said pairs, and holding means individually and detachably arranged between the wires of each pair, thereby allowing the removal of each pair of wires individually without affecting the other pairs.
