Abstract: 18,032. Sabonadier, P., and Eaubonne, E. d'. Aug. 10, 1911, [Convention date]. Coating webs.-Pile threads with multicoloured pattern, for manufacturing carpets and plush-like fabrics, are made by glueing together successive short lengths of threads to form continuous threads, .several of which may be produced simultaneously. To produce " p " different threads each comprising " n " elements, " p " threads are wound side by side on each of " n " successive long spindles a<1>, Fig. 2, to form bobbins or spools carried by plates d' on endless chains d of a distributor driven by ratchet gearing, the spools being inserted in succession in a conveyer f slidable in guides f<1>. The conveyer is actuated by toothed racks f<2> and special mechanism, whereby it is first moved forward and then backwards again for the removal of one spool and tiie insertion of another from the distributor. After the conveyer has been moved forwards, the spool carried thereby is swung downwards by cam- and-lever operated arms p, so that the front ends of the thread are formed vertically over the previously-glued back ends of the previouslyformed continuous threads, which are supported by an intermittently-driven endless lattice or table comprising recessed bars g pivoted to one another and provided with " p " grooves for the threads. An inclined rake or reed o, which is moved backwards and forwards, rides up a guide o<1> and then drops on to the superposed ends of the threads. A vertically-moving and pivoted compression reed k then presses these ends together, and afterwards the conveyer and spool are moved backwards to draw off the required lengths of threads. A second vertically-moving compression reed m then acts on the unwound threads, while the first reed k is swung back on its pivot by cam-and-lever mechanism and is then raised from the united threads, a laterally-moving knife n cutting off the unwound threads. The second reed then rises and the endless table is moved forwards, after which the spool is brought back to the distributor, which advances and brings another spool into action. The continuous threads produced pass under a vertically-movable roller h<13> to a store roller h driven by cam-controlled ratchet-gearing, the engagement and disengagement of the ratchet thereof being controlled by the movements of the roller h<13>. The agglutinant is carried by a vat i, Figs. 2 and 4, which may be provided with a heating arrangement and has rollers i<7>, i<8> engaging with inclined guides i<9>, i<10>. The vat has " p " branches or tubes i<1> provided with needle valves i' connected by a spring-controlled bar i<3>, whereby the valves i<2>, normally close orifices i<5> to the tubes. The bar i' is raised by levers i<11> acted upon by rollers on cam-controlled levers i<13>, spring-controlled pawls i<20> pivoted on the vat normally engaging tappets i<21> and thus locking the levers i<11> when they have raised the bar i<3>. The vat is moved along the guides i<9>, i<10> by cam-and-lever mechaniam, and, when it reaches the lower end of these guides, the levers i<13> are raised and the locking-levers i<20> are, by means of arms i<22> disengaged from the levers i<11>, which are then lowered, the valves i<2> forcing agglutinant down the tubes on to the threads. When the vat rises, the levers i<13> are momentarily lowered and act on the levers i<11> to raise the valves, the locking-pawls i<20> engaging the levers i<11>, while a spring-controlled arm i<32> catches in the upper end of the inclined plane i<10> to hold the vat in position. When the vat moves again, the levers i<13> sink momentarily to disengage the arm i<32>. A cross-bar j, Figs. 2 and 7, of U-section actuated by cam-and-lever mechanism and provided with rollers j<1> guided in grooves j<10>, carries eponges for cleaning the gumming- device. The endless table is cleaned by a rotating cylindrical brush q. A magazine may be used instead of the chain distributor d. Specification 1259/09, [Class 142 (iv), Woven fabrics &c.], is referred to.
