Definitions

• the invention relates to a spreader cylinder, in particular for a weaving machine, with at least one between a closing head and a
• End piece arranged support element on which at least one acting on a fabric web wheel is mounted so that it can not move.
• the prior art is to provide a shaft between the end head and the end piece, on which individual support elements are mounted, these support elements carry the equipped with needles cogs. (DE 195 21 491 Cl)
• Object of the present invention is the opposite, to provide a construction of the type mentioned, in which, if necessary, a single wheel can be removed without affecting the entire spreader cylinder.
• each support member from an inclined to the longitudinal axis of the spreader cylinder first bearing for a single wheel and a spaced second bearing for attachment to one and for removal from the longitudinally of the spreader cylinder extending bearing body consists.
• the support elements are individual parts which can be pushed into the bearing body and pulled out if necessary from this.
• the bearing body may consist of at least one support rod, which extends along the spreader cylinder and on which the individual support elements are spring-loaded.
• each wheel may be formed as an open, provided with a closing area ring, which on at least one arranged on the longitudinal axis shaft between the
• End head and the tail is stored.
• the wheel By designing the wheel as an open ring, it is possible to open or close the ring via the closing area and thus remove the relevant wheel, as well as to mount a new wheel on the shaft.
• each wheel can be provided with one or more closing areas, which can be evenly or unevenly distributed over the circumference. It is conceivable, in particular, to set the wheels together as separate ring sections designed as separate parts which are preferably congruent or identical to each other. The assembled into a complete ring items then form the wheel.
• each individual part has two closing areas adjacent to two adjacent parts (exception: only two parts form a complete ring).
• the closing areas may have a hook construction which engages behind the respectively adjacent closing area of the neighboring element or other connecting means known to the person skilled in the art.
• the cover same design of the individual parts allows the flexible replacement of individual parts instead of the entire wheel.
• the multi-part design of the wheel also allows its particularly easy assembly / disassembly.

• Figures 1 to 5 show a first embodiment of a mash holder cylinder 1 according to the invention for a loom.
• a number of support elements 6 are provided between a closing head 3 and an end piece 4, on each of which a mounted on its outer circumference with needles 8 cog 7 is mounted displaceably (Fig. 5).
• a support member 6 is shown in Fig. 4 and has a to
• first bearing 10 of the carrier element 6 is formed as a cylinder portion 16, on which the wheel 7 formed as a ring known per se is mounted removably.
• the cylinder portion 16 is formed for example as a web 18 bearing point 12th
• the bearing body 14 is formed as arranged between the end cap 3 and the end piece 4 base body 20.
• the main body 20 has storage areas
• the bearing portions 22 are designed as guide grooves 24 for secure displacement storage and removal of the webs 18 of the individual support elements 6.
• the base body 20 may be integrally formed. The shape can be wire-eroded, for example.
• the support members 6 are laterally inserted into the bearing body 14, wherein the webs 18 in the guide grooves 24 of the base body 20 store.
• a comb 26 is also provided, which has individual prongs 28 which engage in the assembled state between the support elements 6.
• the comb 26 extends according to Fig. 1 and 2 along a first side surface of the base body 20 and has at a distance from the tines 28 on the upper side of Fig. 1, 2 and
• a ⁇ ffherelement 33 of FIG. 3 is provided, through which the second bearings 12 of the support members 6 are secured against displacement.
• this opener element 33 lies opposite the comb 26 and extends along a second side surface of the base body 20.
• the comb 26 and the opening element 33 are connected to the bearing body 14 via screws 31.
• Fig. 5 it is shown how the individual wheels 7, which are equipped with the needles 8, store on the respective support member 6.
• the invention is also applicable to other types of wheels, e.g. As wheels with rubber-like outer shell, "wheels without needle”, which have the function of filling rollers, wheels with plastic needles or double wheels on a bearing 10th
• the bearing body 14 may consist of one piece or be screwed together and contains no complicated processing.
• the comb 26 is a bent piece of sheet metal; it prevents the carrier elements 6 from being damaged due to possible machine slide out of the lathe cylinder laterally.
• the support elements 6 are z. B. injected from plastic.
• the opening element 33 has the function of preventing a lateral displacement of the carrier elements 6.
• Bearing body 14 is unscrewed, the individual support members 6 can be pulled over the webs 18 laterally from the respective guide groove 24 of the body 20. This makes it possible to remove or reinsert individual carrier elements 6 without influencing the overall width of the cylinder 1.
• FIGS. 7 to 10 show another possible embodiment of the invention:
• the bearing body 14 ' has two parallel holding rods 34, 34', which are mounted at a distance next to one another in the end piece 4 'and in the region of the end head 3 in a collar 36.
• Each support member 6 ' has shown in Fig. 6 at a distance above the first bearing 10, which is formed in a cylindrical shape 16, two fürgangsöffhungen 38 and 38' for supporting and guiding the two support rods 34 and 34 '.
• each support member 6 ' has a flange 40, in which the fürgangsöffhungen 38 and 38' are arranged.
• each wheel 7 is formed as an open, provided with a closing portion 50 ring, which on at least one arranged on the longitudinal axis shaft between the end cap 3 and the
• the closing area 50 may be provided opposite a joint 55.
• the closing portion 50 in turn can be made of a latch 51 and a
• the closing area of the respective wheel is opened and removed from the shaft by loosening detent 51 and counter-detent 52, after which a new wheel is inserted in this area and becomes functional once the closing area has been closed.
• the hinge 55 ensures easy opening and closing; but it can also be omitted with appropriate material selection.
• a wheel 7 can also be composed of several separate individual elements 7a, 7b.
• Fig. 12 there are two such elements. They extend in the circumferential direction over 180 ° and are congruent to each other. At their ends complementary closing areas or connecting means 50a, 50b are formed. Even more than two individual parts - assuming suitable dimensions - can advantageously be assembled into a ring and also be easily disassembled.
