  • the deflecting beam is constructed'so as to be de- [52] US. Cl 139/114, l39/25,ll3399//1907 formed under the tension force imparted to the ground warp threads during the beating up of the reed 2g fa g 2 vof the loom.
  • the amount of deformation is designed to 1 1e 0 139/97 1 6 A 1 facilitate forward movement of the pile warps during a full beat of the reed.
  • the guide beam can be construc ted in any number of ways and in any number of [56] uNlTE g gg xfigs giiENTs shapes to effect the required deformation.
  • Terry cloth looms have been known to have at least two warp beams, namely one beam for forming the group fabric having relatively tightly tensioned ground warp threads which are to be bound or woven with weft threads, and a second beam for the pile warp threads that are under much less tension or that are, even during the weaving process, in a known way relaxed briefly at suitable intervals of time.
  • the pile warp threads are distributed across the entire width of the warp threads in correspondence to the desired pattern to be woven and are drawn through a shed, and woven into the fabric by means of a reed.
  • pile loops are formed by the pile warp threads in the weaving plane through a periodically effected forward and backward movement of the shed apex relative to the front reversal point of the reed.
  • the individual weft threads are assured of being beaten into the shed apex by the reed, either directly adjoining the finished fabric (full beat), or else at a certain distance from the fabric (partial beat), depending on the desired pileloop length of some 1 to 2 centimeters (cm),in the finished fabric.
  • lfsmooth cloth (without pile loops) is to be produced from time to time during the weaving operation, this can be done by having the reed make only full beats until pile loops are to be made again.
  • the changeover can be by any suitable known process, e.g., by means of a Jacquard mechanism, or an eccentric mechanism, or a cardan-shaft mechanism.
  • the inserted weft threads are at first in fairly loose contact, at the aforesaid spacing from the last threads, while the weft threads beaten in by full beats are in contact with the ground warp threads as well as with the pile warp threads.
  • the last beat for each Weft-thread group is usually a full beat, all the weft threads of the group which had been partially beaten since the last full beat, become pushed forward together along the tightly tensioned ground warp threads, until they become set against the previously formed fabric.
  • the pile-loop threads which are sub jected to but little or no tension, are first, spaced from the fabric between the first partially beaten weft threads, and at the next full beat are pushed forward, together with the partially-beaten Weft threads, and are compacted such that the desired pile loops become formed.
  • the ground warp threads and the weft threads hold the finished ground fabric completely together, and the pile loops stand out, depending on the texture employed, either on one side of else on both sides of the ground weave. 7
  • the warp-thread groups are relaxed either while overcoming a braking force acting on the warp beam (which may be periodically variable) or else are relaxed intermittently from the warp beam by means of a control warp-beam drive.
  • a braking force acting on the warp beam which may be periodically variable
  • different thread tensions are maintained for the ground warp and for the pile warp.
  • the warp-threads group is usually run over a tensioning beam and diverted into the weaving plane.
  • the warp-threads group is then run through a warpthreads control system and forms a shed which is controlled by the weaving shafts.
  • the weft threads are then inserted into the shed and beaten up into the apex of the shed by a reed.
  • the concept of the invention is to make the tensioning beam of a terry cloth loom which is used for the groundwarp threads as a normal relatively massive oscillating beam, which because of the inertia from its mass, at the instant of the-peak tension occurring at the beat of a reed into the threads, opposes a resistance, and thus holds the ground warp threads tautly stretched, while the pile warp threadsare deflected out of a normal thread path by a guide means having a resiliently yieldable guide member.
  • This guide member is used to determine the pile warp thread tension and has as little mass as possible, and thus has only small massinertia. in this way, the'guide member under the influence of the peak tension produced in the pile warp threads by the impact of the reed, yields, and facilitates the described slip-forward movement of the pile warp threads during the full beat of the reed.
  • the guide means for the pile warp threads is made as a non-rotatable deflecting beam having a rigid support extending across the width of a thread-group, and an elastic yielding guide member secured to the support that yields under the influence of varying thread tension.
  • This guide member which can be made of laminated material, has an elongated surface, which is curved and extends continuously in its lengthwise or longitudinal direction across the width of the thread-group, for guiding the pile warp threads.
  • the rigid support may be disposed in a fixed location in the loom housing, and may have any desired cross section, for example, tubular. However, the support may also be mounted so as to pivot about an axis parallel to the longitudinal axis of the support.
  • This construction can in a way known per se be used for controlling the drive of the pile-warp beam in such a way that themean pile warp threadtension can be kept at a constant desired small value.
  • a means may also be provided, in a way known per se that acts on the support, for example, by means of a spring or by utilizing the force of gravity, for the purpose of producing a prestress counter to the pivoting caused by the tension of the warp threads.
  • the yielding guide member is in the form of a band curved similarly to the surface of a cylinder, and enclosing the rigid support part, at least partly.
  • the member can be fastened to the rigid support only at one side; that is, along one longitudinal edge.
  • the other free longitudinal edge is made as a cylindrical surface of a small radius of curvature, so as to avoid any damage to the threads lying thereon.
  • the striplike guide member in order to keep the curvature of the guide surface within limits, may, however, be fastened to the rigid support along both longitudinal edges. With such a form of construction, the danger of dirtying by dust or fluff is substantially reduced.
  • an elastic damping element is disposed between the support andthe inner side of the elastic guide member so that any vibrations produced through the impacts of the reed become effectively countered. Moreover, in this way there is obtained the additional possibility, while using the same strip-material and imparting the same external shape, of making guide surfaces of different flexibility.
  • the support can be made of any desired known material, e.g., an elastic foam-material, or of an inflatable hose.
  • the support can have at least one support surface which is turned toward the inside of the flexible guide member and extends parallel to the longitudinal direction of the deflecting beam, whereby the damping element is held between this support surface and the inside of the guide member.
  • the damping element is compressed between the support surface and the inside of the guide member, and it is possible, through a suitable configuration of the support surface and a suitable curvature of the guiding-member to obtain a certain behavior of the restoring force as a function of the bending of the guide member.
  • the elastically yielding guide member may however also consist of a sheet formed into a closed tube, fastened, through the intermediary of the damping support element, to the rigid support.
  • the tube may, in a position of rest, be disposed concentric of the longitudinal axis of the rigid support. This is particularly advantageous when the support is disposed to be able to turn about its longitudinal axis, so that the warp threads, during weaving, are able to roll over the deflecting beam, instead of sliding. The warp threads can thus receive particularly careful treatment, and undesirable rubbing and friction is avoided.

  • the method of attaching the rigid support to the machine frame, or its position in its operative state may be altered as desired.
  • any other bending-resistant form of construction e.g., a double-T or an angle-profile, may be provided.
  • the damping element may be fastened to the rigid support and, in the position of rest, not contact the inner side of the yieldable guide member but do this only after a certain bending (deformation) of the guide member has occurred.

The essential thing is only that the guide member shall be elastic and easily deformable, and have a small movable mass.
  • Deflectin'g beams of the described kind may be installed in a loom for special purposes, and also for purposes other than that of a pile-warp beam. Also, these deflecting beams do not need to extend across the entire weaving width of the machine. It suffices for their length to be suitable for the width of the group of threads to be deflected thereby. Thus, for example, it is possible to imagine that over a part of the width of the weave of a special pattern, or in the case of special designs, a part of the warp threads consists of fancy yarns, particularly delicate or elastic yarns, that have to be woven with less thread tension than ordinarily.
  • deflecting beam according to the invention use may also be made of a deflecting beam according to the invention, without the threads-group concerned, and thus the deflecting beam, having to extend across the entire width of the weave. It is also obvious that the deflecting beam of the invention may also be used to deflect normal ground warp threads.
