Definitions

  • A Debonnet BY VB-241V A TTO LNEBS SHEET 3 BF 3 INVENTOR.
  • Such a combination of folding and auxiliary blades is known for instance in a machine wherein a series of threads are folded loop-shaped into a well.
  • An object of the present invention is the provision of a device which totally eliminates the aforementioned as well as other drawbacks of the existing devices.
  • the present device mainly consists in a construction wherein aforesaid folding blades are each connected to a system of pivoting levers, whereby each system is controlled by a system of cams or the like which temporarily maintain one folding blade in its lowest position whilst the second folding blade starts its downward stroke in order to deviate the set of threads.
  • FIGS. 1 to 6 schematically show the kinetic movements of the folding blades, as they are used in the device according to the present invention
  • FIG. 13 shows a diagram of the movements carried out by the folding blades of the device according to FIGS. 1 to 13;
  • FIG. 14 is a larger scale illustration of an embodiment of the device according to this invention.
  • FIG. 15 is a schematic topview according to arrow F15 of FIG. 14.
  • Levers 9 and 11 are pivotally fixed at their other end upon pivots, 13 and 14, whilst levers l0 and 12 are pivotally connected at their other end by means of pivots 15-16 with levers 17-18, which at their other ends are fixed to pivots l9 and 20.
  • the pivots 13-14 and 19-20 are fitted in bearings which are fixed with respect to the machine.
  • the movements of aforesaid folding blades 1 and 2 are determined in such a way that they act upon the ridges 21-22 of the well 23 in which the backing layers 24-25, and the loops 26 are fed.
  • Cams 27-29 are fixed upon shaft 39 and cams 28-30 upon shaft 40.
  • Both blades 1 and 2 act successively upon the ridges 22 and 21, of aforesaid well 23.
  • the movement of the folding blades 1 and 2 with respect to each other is such, that when for instance blade 2 has just formed a loop, see FIG. 7, folding blade 1 is in its retracted position, after which, whilst blade 2 remains against ridge 21, blade 1 is brought forward almost against blade 2 and this in such manner that threads 26 have already been formed for the pressing in position of the following loop before the previous loop is released by blade 2.
  • blade 2 When both blades are in the position shown in FIG. 9, blade 2 will move further backwards, whilst blade 1 forms a loop and brings the latter toward ridge 22, see FIG. 10.
  • blade 2 is brought in identical manner against blade 1 in order to prepare the next loop, see FIG. 11, whereby this blade is maintained in this position until blade 1 has moved backwards, see FIG. 12. Blade 1 is next brought back to the position shown in FIG. 7.
  • FIG. 13 the diagrams have been drawn of the paths followed' by blades 1 and 2 in the course of this operation, whereby the path of blade 2 is shown in solid line whilst the path of blade 1 is shown in striped line.
  • the movements of blades 1 and 2 are determined in such a way that the paths followed correspond to diagram A B C A for blade 2 and to diagram A, B C, A, for blade 1.
  • Blade 2 will remain for instance during one-fourth turn of shaft 40 in this position, whilst during this time blade 1 will move from point A, along B to D,, thus already preparing the following loop whilst blade 2 maintains the preceding loop pressed into the mass of glue upon backing layer 24.
  • blade 2 will retract from C to A, after which blade I will be further displaced to C, thus forming the new loop.
  • the movement of blade 1 along path D, C is preferably given a circular shape, with ridge 21 as center, so that the threads remain under constant tension during the formation of the loop, without having to be subjected to pull.
  • the blades shall each be maintained during one-fourth turn of shafts 39 and 40 in their respective locations C and C
  • the displacements from C to A and from C to A will also take one-fourth turn of shafts 40 and 39; the displacements A B-D and A-B-D will also occur during one-fourth turn and the displacements D -C and D-C in the course of the last one-fourth turn of shafts 39 and 40.
  • pivots 13-14 and 19-20 can be obtained in any manner whatever, such as for instance by means of jacks, electromagnets, etc.
  • the paths D-C and D,C are preferably of circular shape the centers being the ridges 22 and 21, although these circular paths could just as well be drawn around centers which are located higher or lower than the horizontal plane which passes through the points CC whereby in such cases for instance the walls of well 23 should be made diverging in the one or in the other sense.
  • the movement of the folding blades is also by no means limited to the paths as shown in the diagrams of FIG. 13. In fact the movements of the folding blades can follow any appropriate path, whereby said path can be brought about by any appropriate means.
  • the present invention is by no means limited to the example described and to the form of embodiment illustrated by the appended drawings, but extends to all devices in which one folding blade maintains a loop pressed in position whilst the other blade prepares the next loop.
  • a device for producing a nonwoven carpet made from two backing layers coated with glue and fed into a well and a set of threads between the loops comprising, in combination, folding blades acting alternately upon the set of threads to form loops between the layers, rods, each folding blade being fixed to the free end of a rod, levers, each rod being pivotally connected at its other end to a lever, shafts, said levers being fixed to said shafts, bearings supporting said shafts for rotation, other levers pivotally connected with said rods intermediate their lengths, third levers pivotally connected with said other levers, bearings supporting said third levers, rods connected with said shafts for imparting angular displacements to the shafts, cams actuating said rods, and means actuating said cams to maintain one folding blade temporarily in its lowermost position while a second folding blade starts its downward movement and deviates the set of threads.
