Definitions

  • This ⁇ invention relates to a process and a device for feeding threads, wires and the like to a roll for forming a net with threads and the like intersecting each other diagonally of the longitudinal direction.
  • the ⁇ depositing of the threads on the roll to form a net with threads intersecting diagonally of the longitudinal direction takes place accurately for as long as the chain runs carrying the sleeve advance in a straight line.
  • the endless chain is, however, deflected at the end points. Due to this deflection, the predetermined ratio of the chain rotation speed to the travelthr-ough speed of the net or the peripheral speed of the roll is changed. During the deflection, the chain links and therewith the sleeves guiding the threads carry out an unequal, translatory movement. Furthermore, the deection circle is rel-atively large.
  • the laying device must be ⁇ arranged at a relatively considerable distance from the roll so that the threads are compelled, from the instant at which they leave the sleeves until the instant at which they bear on the roll, to travel over a relatively long path during which they are not guided.
  • the result of this is an accumulation of threads along the marginal zone of the net to be formed.
  • the threads extend, at the edge of the net, arcuately from a more or less considerable radius. This kind lof formation of the threads in the marginal Zone is not desirable.
  • the invention relates to a further advantageous mode of feeding the threads or the like in the manufacture of a net having threads intersecting diagonally of the longitudinal direction.
  • the deflecting of t'he threads at the edge of the net takes place practically without noticeable rounding off curves.
  • the threads are, during the deflecting process, guided round through 180 from the advancing run to the rearwardly Patented Nov. 8, 1966 ice travelling -run of the laying device relative to the thread division resulting from the spacing at an angle of inclination of approximately relatively to the longitudinal axis of the laying device.
  • the threads are, during the deflecting process, guided round through 180 from the advancing run to the rearwardly Patented Nov. 8, 1966 ice travelling -run of the laying device relative to the thread division resulting from the spacing at an angle of inclination of approximately relatively to the longitudinal axis of the laying device.
  • the at design makes it possible to position the laying device close up against the roll.
  • the laying device can, due to its low height, be positioned near the roll gap. Due t-o the very considerable translatory movement of the sleeves guiding the threads during deflection in the laying device accumulation of the threads at the end of Jche net to be formed can be avoided.
  • the threads intersect lat the edge of the net to be pitch extends over a deflection path ⁇ corresponding to 90.
  • the means for driving the threadslaying chain is disposed on the outer sides of the runs.
  • the guide rails insure rectilinear travel of the runs.
  • FIG. 1 is a central longitudinal vertical sectional View through an embodiment of the invention and shows diagrammatically the details thereof;
  • FIG. 2 is a half section horizontal sectional view taken through the center of the spool cage shaft.
  • FIG. 3 is a fragmentary end View of the appara-tus of FIG. 4 is an enlarged elevational view showing schematically the details of the thread-laying device according to the invention
  • FIG. 5 is an enlarged fragmentary elevational view showing schematically the passage of a roller chain about an associa-ted guide rail;
  • FIG. 6 is an enlarged schematic elevational view and shows the driving arrangement for the device according to the invention.
  • FIG. 7 is an enlarged fragmentary plan view sche ⁇ matically showing the feed of the threads to the roll.
  • FIG. 8 is an enlarged fragmentary end view schema-tically showing the feed of the threads to the roll.
  • the device has a spool or bobbin cage 1 on which 4thread or wire spools 2 are-arranged in Iany desired number.
  • the spool cage 1 is mounted for rotation about a shaft 3 projecting unilaterally out of a frame 4.
  • a conveying roll 5 over which pass the threads 6 off from the spools 2 for the purpose of forming a net.
  • the threads 6 pass through a thread-laying device 7 with the aid of which a net having threads intersecting diagonally of the longitudinal direction of the net is formed.
  • the roll and the thread-laying device 7 are mounted in a frame 8. It is possible to arrange a further roll 9 for cooperation with the roll 5, the net to be formed then passing between the -two -rolls 5 and 9.
  • the net formed can be used for the reinforcement of Webs of paper or the like.
  • webs 10 and 11, which -are drawn off from supply drums 12 and 13, also mounted in the frame 8, may simultaneously run in between the rolls 5 and 9.
  • At least one web, for example the web 10 can be sprayed with a bonding argent, for example, an adhesive bitumen or the like, from a container 14, so that the webs 10 and 11 are, as they pass through the rolls 5 and 9, joined together in such a manner as to enclose the thread net.
  • a composite web 15 reinforced in this manner is guided ove. detlecting rolls 16 and 17 and Wound up on a roll 18.
  • the thread-laying device 7 is so designed that it consists of two independent chains 19 and 20, as is shown in FIG. 4.
  • the chain 19, which is an endless chain, is a ydrive chain which is guided about chain sprockets 21.
  • Disposed between parallel runs of the -drive chain 19 is a thread-laying chain 20.
  • This chain being expediently designed 'as a roller chain, has rollers 22 formed with longitudinal bores 23 through which the threads 6 drawn off from the spool cages are guided.
  • the endless roller chain runs about a guide rail 24.
  • the guide rail 24 is tloatingly mounted tbetween the runs of the roller chain 20.
  • the drive chain 19 is provided with drive members 25 which engage between rollers 22.
  • the guide rail 24 remains in situ together with the threadlaying chain 20 surrounding it, since the displacement forces exerted by the drive members 25 act in opposite direction in the two runs cancel ea-ch other out completely.
  • the guide rail 24 can be for-med at any desired points, in particular at its ends, with bores 26 through which tensioning or longitudinal threads or wires can be guided. Shortly before the chain sprocket 21 the -drive chain 19 travels over rolls 27 and 28 by means of which the drive chain 19 can 'be ykept tensioned.
  • a plurality of juxtaposed thread-laying chains 20 is disposed between fthe 4runs of the drive chain 19. This is an expedient arrangement if the reinforced paper web 15 is to be divided up into a plurality of longitudinal strips. With this arrangement, the net edges are retained, undamaged, in the reinforced paper web.
  • the thread-laying chain 20, can, however, also rotate over the entire width of the paper web.
  • the subdivision according to the invention of the thread-laying device into a chain guiding the threads and la drive chain engaging from the exterior on the threadlaying chain makes it possible to position the runs of the thread-laying chain 20 relatively close together.
  • FIG. 5 shows, the smallest deflection of the chain 20 about the guide rail 24 is effected at an angle of 45 and in such manner that the pitch t of the chain 20 extends over a half deection path which extends through an angle of 90. Since the chain sprockets 21 of the drive chain are disposed externally of the length of the 'roll 5 and/or the roll 9, the thread-laying device can be displaced to a point relatively close to these rolls. The free ⁇ length of the threads over which the latter are unguided can be kept extremely short.
  • the threadlaying chain 20 is expediently a roller chain in the form of a double strap chain having inner straps 29 and outer straps 30.
  • the drive can, for example, be as follows (FIGS. l and 6):
  • a sprocket 32 is driven by a motor 31.
  • the sprocket 32 provides, by means of shafts and further intermediate wheels and a belt or chain 33, a drive for a sprocket 34 which .may directly drive sprocket 21.
  • the spool cage 1 is driven by a sprocket connected to the sprocket 34 land a chain or t-he like 35 through a sprocket 36 and through further gears 39 and 40.
  • the drive for the roll 5 is driven by means of the sprocket 32 through a gear 41 and sprocket 42 and 44 and a belt or chain 43. With one rotation of the chain 20, the spool cage 1 is also compelled to rotate once.
  • the Aratio of the rotation speed of the chain 20 to the travel-through speed of the net formed which is practically identical with the peripheral speed of the roll 5, varies with the angle of inclination of the threads or wires on the roll 5 to the through-travel direction of the net.
  • the ratio of the through-travel speed of the net, which is identical with the peripheral speed of the roll 5, to the rotation speed of the chain 20 is 1 to l.
  • the -mesh formed in the net is, in this case, square. Depending on the variation in the speed ratio, it is possible to form mesh which is longer in the direction of Imovement of the net or in the width direction than in the direction transversely thereof.
  • the net formed serves for the reinforcement of paper webs.
  • the mesh can also be secured by ⁇ being welded together with a suitable device at the points of intersection.
  • Any appropriate type of thread can be used, for example, threads of textile material, plastic, glass and the like. I-t is, however, also possible to use metal threads.
  • a thread laying device comprising an endless drive chain having parallel intermediate runs, a guide rail disposed intermediate said drive chain runs, an endless thread laying chain mounted on said guide rail for movement therearound, said thread laying chain having thread sleeves, and drive members on said drive chain engaging and driving said thread laying chain -above and below said thread laying chain so that said thread laying chain maintains the same relative position, said thread laying chain and said guide rail lbeing floatingly supported by said drive chain.
