Definitions

  • the invention relates to a spreader for holding or laterally tensioning a fabric, in particular on looms, with an endless guide in which links provided with needles for engaging the fabric are slidably arranged and the guide extends and is arranged such that the needles are at least two Links engage at the same time with the edge of the tissue and the needles that come into engagement with the tissue are at a greater distance from the longitudinal axis of the tissue web when they are needled than when they are needled.
  • the spreader bars can be used on all types of textile machines that are traversed by fabric webs, e.g. Tensioning, steaming, shrinking, drying, fixing and finishing machines.
  • Spreaders of various types have already become known.
  • the spreader In the first type, the spreader extends across the entire web width and runs parallel to the weft threads.
  • the fabric is usually guided in a partial wrap around thread or needle rollers.
  • the main disadvantages of such spreaders are an uneven transverse tension and the fact that they are complex and complicated and mostly difficult to handle.
  • An arrangement has proven to be particularly expedient here, in which in each link a recess running in the longitudinal direction of the link is provided, into which an approximately rod-shaped piece of material made of a rubber or plastic material is inserted, which has a length such that when this is applied Buffer on the next link without effect of a compression force exerted on the links, the links have at least a distance which corresponds to the part of the overall game that results when the overall game is evenly distributed among all adjacent links.
  • Polyurethane has proven to be a particularly useful buffer material.
  • a plurality or all of the adjacent links on their mutually facing sides are each bevelled inward towards the guide, and a pusher link is arranged between each two adjacent, opposing links, each of which moves when the links move endless guide is taken with and there is provided in a region of the endless guide, in which the links are out of engagement with the fabric web, a resiliently projecting cam track in the path of movement of the tappet members, which during the overrunning the tappet members in one opposite the adjacent links holds displaced position, in which the pusher links the adjacent links each keep a distance from each other.
  • the tappet members preferably consist of balls, cylinders or wedges. Such an arrangement is extremely durable and practically maintenance-free.
  • the cam track is expediently formed by a spring preloaded by a spring which, in the event of a pressure exerted on the members out of engagement with the fabric web, in the direction of mutual contact via the tappet members counter to the spring force of the spring into an outside of the original movement path of the tappet members Position can be brought. This allows the play between the one or some links that are out of engagement with the fabric web to be increased or decreased as desired depending on the compression pressure applied to the links.
  • the first leg 20 carries on its side facing away from the second leg 21 a plurality of needles 23 which run essentially perpendicular to the first leg 20.
  • a projection 24 is formed which, as can best be seen from FIG. 4, is essentially in the form of a rectangle, but which is spherically shaped on its upper side 25 and rounded at its ends.
  • the second leg 21 has on its side facing away from the first leg 20 a projection 26 which can be formed, for example, by a pin inserted into this second leg 21.
  • the link 8 is practically a mirror image of the plane perpendicular to the plane of the drawing and extending through the longitudinal axis 27.
  • the side edges 28 and 29 (FIG.
  • the total play G must be greater than or equal to the longitudinal extension b of the material between the first pin point and the last pin point plus the length (n + 1) xa, ie G ⁇ b + (n + 1) xa be, where n is the number of gaps between the maximally needles pinned with the fabric web.
  • the mode of operation of this embodiment is as follows: When the web of fabric moves forward by the length of the distance between two links 92, 93, the star wheel is rotated further by the angle between two stars. Here, one of the stars first comes into engagement with the second arm 109 of the double-armed lever 107 and pivots it counterclockwise around the articulation point 108. Here, the slide 103 is moved back against the direction of advance 102 and against the force of the spring 112, the driver 104 passing through the slight pivoting of the slide 103 is slightly raised. As soon as the star comes out of engagement with the arm 109 again during its further movement, the slide can move forward due to the spring 112 after it has reached behind the next link 96 with its driver 104 during its backward movement.
  • the guideway was generally designed in such a way that, with appropriate pressure on the limbs, it made it possible to extend the path, which was at least as large as the total game required.
  • the individual links can thus be arranged in the guideway without virtually any total play. The necessary "play” then only arises during operation by extending the guideway.
  • the operation of this device is as follows:
  • the driver 104 'of the slide 103' is due to the force of the compression spring 112 'against the rear end of the link 97'.
  • the slider continues to advance in the direction of arrow 102 '.
  • the rear end 131 of the slide and the armature 132 of the electromagnet 130 thus move.
  • the normally open on / off switch 134 is closed, as a result of which the electromagnet 130 is excited.
  • the armature is moved together with the slide 103 in the direction of the arrow 105. That is, the driver 104 'is withdrawn and slides over at least the next free link 96'.
  • each link 140, 141, 142, etc. are already needled with the fabric sheet 143.
  • the movement of the fabric web 143 is in the direction of the arrow 144.
  • the links 145, 146 and 147 In front of the last needled link 140 are the links 145, 146 and 147, which are mutually in contact and in particular in contact with the last needled link 140.
  • each link On its side facing away from the fabric web 143, each link has a first flank 148 that slowly rises in the direction of movement of the fabric web and a second flank 149 that falls somewhat more steeply.
