- Lobato ABSTRACT Tension plate for holding woven fabric over all its width, comprising a fixed plate the front edge of which is turned down to form a lip, the edge being surrounded, after interpositioning of the fabric by a mobile floating-oscillating section composed of a face substantially parallel to said plate for applying on aid plate and a face substantially following the contour of said lip and extending backwards of said lip.
- lateral tension-frames each constituted by a substantially cylindrical part swiveling freely and in which are cut spiral grooves where a large number of spikes protrude; the edge of the woven fabric passes on this cylinder, under a casing; the loss of these tension-frames is very high, taking into consideration the careful operation that is necessary failing which they damage the tissue, diminish its value and cause weaving problems; additionally, the maintenance of the woven fabric essentially by the edges deforms the weft line, alters the number of warp threads per centimeter etc.; on the other hand, the sharp spikes used noticeably mark the fabric.
- the present invention which has for aim to avoid all of these disadvantages, has for object a new tension-frame holding the fabric over all its width.
- It is characterized in that it comprises a fixed plate, the front edge of which is bent over towards the bottom to form a lip, this edge being surrounded, after interpositioning of the fabric, by a mobile section (floating-oscillating), composed, to support itself on the upper surface of the plate, of a plate parallel to that joined to a descending surface until a fold situated slightly below the said lip, before being brought above and behind that.
- a mobile section floating-oscillating
- FIG. I a schematic cross section of a device according to the invention.
- FIG. 2 the device of FIG. I with its weft cut
- FIG. 3 an assembly device of two sections end to end.
- a fixed part or support plate 2 serving as base and which is an angle bar with a having a leading edge or lip 3 of special shape;
- a mobile part or movable clamping member 4 floating-oscillating which is a bent over section.
- This can have on the lower lip 5, a smooth edge or a notched or threaded edge 6 comprising a clamping means for clamping the fabric 1 against the leading edge 3.
- This edge 6 can be separately provided from this mobile part, then fitted thereon; an example is given in the drawing.
- the oscillating section 4 constrains the fabric 1 to turn about the fixed nose 3.
- This oscillating section 4 thus forms a lock.
- the tension of the fabric I applies this section 4 against the nose 3 which prevents it from escaping, thus giving autoclamping.
- the contact of the fabric 1 is thus provided between the surface portion of the edge 6, itself covered by the fabric I, and the interior surface of the lip or nose 3.
- the edge 6 has ribs inclined in opposite directions displaced from the longitudinal axis and moving and separating from each other in the direction of movement of the fabric to keep the fabric 1 over all its width.
- the advance is caused upon each insertion of a weft thread.
- the oscillation enables sliding, but upon withdrawal of the comb the autoclamping prevents any backward movement.
- the two parts 2 and 4 can be modified from those illustrated, notably in relation to the cross sections of the section 4 and of the angle bar 2.
- the sheet having only one straight line from one edge to the other.
- the width of the tension-frame is easily adjustable, which is indispensable for this type of tension-frame.
- oscillating sections 4, as well as the edges 6 can be joined up or cut by their middle to change the width of the fabric 1.
- two T-squares 11 laterally space the various joined up elements of the oscillating section, a housing being provided for the T-squares at the extremities of this section 4.
- the nose 3 can also be reinforced, to increase its pressure at the edges.
- a special weft cutter 7 can easily be positioned near to the edge.
- This weft cutter is composed of a needle 8 with hook 9 displaceable backwards; this movement is caused by the batten in the rearward direction and corresponds to the cutting operation.
- the needle is pushed forward again by a spring.
- the weft cutting apparatus 7 is easily positioned under the fixed section 2. Its height is preadjustable and the width position is eased by a line of holes provided on the edge of the said fixed section 2.
- An apparatus for releasably clamping an intermittently advancing fabric web in its advanced position comprising: a fixedly mounted support plate and a movably mounted clamping member disposed in the path of travel of an intermittently advancing fabric web and cooperative together to releasably clamp the web therebetween; said support plate having an arcuate leading edge disposed transverse to the path of travel of the fabric web dimensioned to slidingly receive therearound the fabric web; said clamping member having an arcuate configuration substantially enclosing said leading edge of said support plate and including at one end thereof clamping means for releasably clamping the fabric web against said leading edge in response to movement of said clamping member; and means mounting said clamping member for movement relative to said support plate to enable said clamping means to releasably clamp the fabric web against said leading edge in dependence upon the degree of tension externally applied to the fabric web.
- clamping means comprises an arcuate surface having a profiled portion complementing a surface portion of said leading edge to effectively clamp the fabric web between said arcuate surface and leading edge in response to movement of said clamping member.
- An apparatus including a plurality of ribs positioned on said arcuate surface to increase the clamping effect of said clamping means.
- a tension plate for holding woven fabric at the output of a loom over its full width comprising: a fixed plate, a lip on a front edge of said plate having a rearwardly facing surface, a movable floating-oscillating member loosely mounted on said front edge and including two arms spaced one on each side of said front edge, a first arm having at least a portion extending towards the second arm, said portion having a surface cooperating with the rearwardly facing surface of said lip to effectively grip the fabric therebetween.
- a tension plate according to claim 4 wherein said fixed plate has a horizontal surface and said movable member has a substantially horizontal surface above the longitudinal surface of said plate, a substantially vertical surface below said horizontal surface and said first arm being bent back at the bottom of said vertical surface.
- a tension plate according to claim 8 wherein the surface of said movable member cooperating with the rearwardly facing surface of said lip comprises a threaded element.
