Definitions
- the invention relates to a tray shortage according to the preamble of claim 1.
- Trough mangles have one or more consecutive in shortage direction rotatable drivable mangle rolls, each of which is associated with a heatable mangle trough.
- the or each mangle roller is provided with a winding.
- the winding consists mainly of a textile or fibrous material.
- the winding is formed from a over the entire width of the respective mangle roller continuously extending blank. This blank is so long that it is wound once or possibly twice around the mangle roll.
- the blank is made endless by connecting its adjacent free transverse edges. There, where the transverse edges are connected, creates a parallel to the axis of rotation of the respective mangle roller running continuously
- the blank to form the Mangelbewicklung is connected at its opposite transverse edges by sewing and / or gluing.
- Such a connection has not been proven in practice. The connection does not last the entire life of the winding and occasionally ruptures. It also happens that the joint, especially when it is older, forms a gap that leaves a pattern on the mangled linen.
- the invention has for its object to provide a tray deficiency, the winding can be done easily and permanently endless, without the seam affects the quality of the defect.
- a tray deficiency to solve this problem has the features of claim 1.
- the winding by needles and / or Ketteln is made endless. Both the needling and the linking are done with a variety of stitches. The number of stitches when needling and Ketteln is many times greater than ordinary sewing. The needling and / or warping thus creates a very reliable permanent wrapping endless. Above all, the close stitches result in a much more homogeneous connection than is the case when sewing. As a result, the endless cutting of the winding according to the invention does not adversely affect the defect quality.
- the endless wrapping works in terms of durability and also the defect quality like a quasi endless winding.

- a particularly advantageous embodiment possibility of endless wrapping by needling and / or warping is characterized in that the transverse edge regions are connected to each other with overlap.
- the overlapping transverse edge regions of the blank are compressed, above all, during needlepunching, but also during the chaining as a result of the many punctures, so that the connection edge strip, despite the overlapping edge regions in its region, has a thickness which is adjacent to the thickness of the blank or the wrapping on both sides the Connecting strip corresponds.
- traversed transverse edge areas with overlapping in their occupied areas are connected to one another by needling and / or warping.
- a connecting strip is created, which is not or at least not appreciably thicker than the blank of the winding.
- An advantageous embodiment possibility of the connected connection of the transverse edge regions of the blank of the winding provides to reduce the transverse edge regions in the thickness so far that after connecting the overlapping transverse edge regions by needling and / or gluing the thickness of the connecting strip about the thickness of the blank of the winding , So the thickness of the remaining blank, corresponds.
- the reduction in the thickness of the transverse edge regions can be chosen so that the winding in the region of the connecting strip is no longer thicker after the continuous drawing according to the invention than in the adjacent regions. This creates an endlessly wound with completely the same thickness and a virtually no-going edge seams.
- the reduction of the thickness of the blank of the winding takes place in the region of the transverse edge regions to be joined by a gradation or chamfering of at least one transverse edge region, preferably both transverse edge regions.
- a connecting strip can be selectively formed which, after needling and / or kneading, lies seamlessly between the regions of the blank adjacent to one another on both sides, thus creating a virtually endless winding.
- the grading or chamfering of at least one transverse edge region of the blank for the defect wrapping takes place in such a way that the transverse edge regions which overlap in the region of the connecting strip have, prior to joining together, a thickness which is 1, 1 to 8, 8, preferably 1, 2 to 1, 6 times, the thickness of the cut of the winding
- This thickness is reduced to about the thickness of the blank of the winding after needling and / or Ketteln or by needling and / or Ketteln. It is compressed by the needling or Ketteln the blank in the region of the connecting strip or compressed to a lower compared to the initial state before needling or Ketteln thickness, namely the thickness of the blank.
- the textile or fibrous material of the winding is a woven fabric, a felt, in particular a needle felt and / or thick felt, or a fiber material.
- a woven fabric a felt, in particular a needle felt and / or thick felt, or a fiber material.
- these are usual materials for winding of trough mangles.
- the invention does not require to form the winding of a different material.
- the blank made from commercially available materials can be made endless by needling and / or warping, virtually seamlessly.
- the textile or fibrous material of the winding of synthetic fibers or synthetic fibers is characterized by a high temperature resistance required for the deficiency operation or the winding may be formed from a material which has the high temperature resistance required for trough mangles.
- the winding of the trough mangles can be single-layered or multi-layered, for example two-ply.
- the at least one double circumference blanket of the mangle roll is wrapped around it twice, and only adjacent transverse edge areas of the needling and / or warp wrapping are made endless.
- the invention is also suitable for trough mangles in which a bottom suspension is provided between the outer shell of the respective mangle roll and the inside of the winding.
- a bottom suspension is provided between the outer shell of the respective mangle roll and the inside of the winding.

- a spring base It may be provided between the winding 21 and the lateral surface of the cylindrical mangle roller 11, a spring base.
- This is usually formed from a plurality of leaf spring-like trained individual springs, which are interconnected and thus linked to form at least one circumferentially spirally around the mangle roller 11 wrapped around the spring strip.
- the winding 21 of a rectangular blank is made according to the invention in a special way endless. This is done according to the embodiments of FIGS. 3 to 6 by needling and in the embodiment of FIGS. 7 and 8 by coupling.
- opposite transverse edge regions 25, 26 of the blank of the winding 21, the transverse edges 23, 24 lie next to each other after laying the blank around the mangle roller 11, in particular directly to each other, connected to each other by needling or Ketteln. This results in the connection point for continuous winding of the winding 21, a connection, in particular a parallel to the longitudinal central axis 15 of the mangle roller 1 1 extending connecting strip 22.
- the connecting strip 22 has a length (seen in the direction of defect 14), that of the respective transverse edge region 25 and 26 corresponds.

- the thickness of the winding 21 will also be less when using a thick felt for the winding 21, in particular for smaller trough mangles with correspondingly smaller diameter mangle rolls 11.
- FIGS. 3 and 4 are for continuous production of the winding 21 of opposite transverse edges 23 and 24 of the blank of the winding 21 outgoing, equal width transverse edge regions 25, 26 opposite beveled, to the same extent.
- the same chamfers 27 formed thereby are chosen so that they correspond to the width of the connecting strip 22 and still a narrow strip of the respective transverse edge 23, 24 stops, so that the chamfers 27 terminate dull.
- the width or height of the remaining transverse edge 23, 24 is selected so that after the endless cutting of the blank to form the closed cylindrical winding 21, a continuous transition to the other sections of the blank adjoining the connecting strip 22 on both sides (FIG. 4).
- the transverse edge regions 25, 26 Prior to the continuous cutting of the formation of the winding 21, the transverse edge regions 25, 26 are superimposed. In this case, the same direction and equal width chamfers 27 congruent to the system (Fig. 3).

- a plurality of stitch lines 28 thus follows closely to one another (FIG. 4). In the region of the stub lines 28, fibers of one transverse edge region 25 are drawn into the other, overlapping transverse edge region 26, so that each transverse edge region 25, 26 contains fibers from the other transverse edge region 25, 26.
- the winding 21 is made endless by needles.
- This embodiment differs from that of FIGS. 3 and 4 only in that instead of the chamfer 27, a step in each transverse edge region 25, 26 is provided.
- the gradation 29 comes through a seen from the side of the winding 21 rectangular material removal, which extends over the entire width of the transverse edge region 25, 26 (seen transversely to the defect direction 14).
- Both for the formation of the gradation 29 serving rectangular material Abtrag or -aus bainitese in the transverse edge region 25 and 26 are the same size.
- the blank in the region of the gradation 29, that is to say the respective transverse edge region 25, 26, preferably has only 55% to 90%, in particular 60% to 80%, of the total thickness of the blank.

- the material of the blank for the winding 21 is so much compressed or compressed in the transverse edge regions 25, 26 in that the connecting strip 22 after needling has the same thickness as the initial thickness of the blank of the winding 21.
- the winding 21 is made quasi continuous or transitionless endless by the inventive method. The winding can thereby cause at the junction, namely in the region of the connecting strip 22, no impairment of mangled laundry.
- the continuous endless winding of the winding 21 is due to the fact that the reduction in the thickness of the transverse edge regions 25, 26 in the region of the gradation 29 of the connecting strip 22 is selected so that after the Needling the stepped, overlapping transverse edge regions 25, 26 have been compressed so much that they are the same thickness as the adjoining regions of the winding 21.
- the winding 21 has, after being wound up by needles, over its entire circumference , Also in the region of the connecting strip 22, over an at least approximately the same thickness.
- the winding 21 is made endless by connecting the transverse edge portions 25, 26 to form the connecting strip 22 by lacing.
- the blank wrapped around the mangle roll 11 is stretched elastically so that it extends slightly.
- the transverse edge regions 25, 26 can be bent or angled by about 90 ° so that they run radially to the mangle roller 11 and their transverse edge regions 25, 26 are at least partially superposed.
- the transverse edge regions 25, 26 are not dealt with in this embodiment by being provided with bevels 27 and gradations 29, respectively.
- transverse edge regions 25 and 26 By bending both transverse edge regions 25 and 26, the transverse edges 23 and 24 of the blank are juxtaposed on a line. This line is directed away from the lateral surface of the mangle roller 11 and spaced therefrom. In this case, the adjacent transverse edges 23, 24 may lie on an arcuate line which runs concentrically to the lateral surface of the mangle roller 11, but with a radius which is greater than the radius of the mangle roller 11.
- the transverse edge regions 25, 26 are now connected by kettling, whereby a plurality of closely spaced closed loops 30 are formed around the transverse edges 23 and 24.
- the loops 30 extend thereby with one half of their length spaced from the adjacent transverse edges 23 and 24 by closely behind lying points of the transverse edge regions 25 and 26 and the other half outside in front of the transverse edges 23, 24 along (FIG. 7).
- the elastic elongation of the blank is reversed again and thereby the bending or bending of the transverse edge regions 25, 26 is automatically canceled and / or reversed by the internal stress of the blank.
- the cut contracts so again. He shortens himself.
- the transverse edges 23, 24 of the blank are oriented in such a way that they again run parallel to one another and preferably touch each other, ie lie close together (FIG. 8).
- the loops 30 formed by the linking are thereby reoriented, namely from an originally horizontal oval (FIG. 7) into a vertical and preferably shorter oval (FIG. 8). In this case, the threads of the loops 30 slip through the material of the blank.
- the winding 21 is made endless by Ketteln, without requiring a Schftelung the transverse edge regions 25, 26 in the region of the connecting strip 22 is required.
- a smooth, smooth connection is formed with a connecting strip 22 which corresponds to the thickness of the blank.
- This also makes the winding 21 endless, without any discontinuity in the region of the connecting strip 22, that is to say the connection of the opposite transverse edges 23, 24 of the blank of the winding 21, a thickening, bulge or a discontinuity in any other way Endless wrapping 21 is created by Ketteln.
