Definitions
- the invention relates to a device on a carding machine in which at least one working and / or covering element of a garnished roll is arranged at a distance from one another and extends over the entire width of the roll, which comprises an elongated supporting body comprising a foot part and a back part has two side walls and the back part is equipped on its outwardly facing surface with a thermal insulation.
- CONFIRMATION COPY passes. This in turn creates a temperature gradient between the clothing side of the flat rod (warm) and its back (cold). It is this temperature gradient that is responsible for the deformation (towards the drum) of the rod.
- the carrier profiles for carding elements are today designed as completely closed aluminum extruded profiles.
- the heat generated during the carding process is dissipated to a large extent via the carding to the outside.
- the necessary temperature gradient within the profile cross-section leads to deformation of the carding element. The greater this gradient, the greater the deformation.
- a flat bar in which the carrier plate is equipped on its outwardly directed surface with a thermal insulation.
- the heat insulation extends over the entire lid back height, with no heat can be dissipated by the lower insulated part of the lid back.
- the invention is therefore an object of the invention to provide a device of the type described above, which avoids the disadvantages mentioned, in particular the working and / or the cover, z. B. the flat bar, remains dimensionally stable during operation even when exposed to heat.
- the temperature gradient of the lid is reduced.
- the temperature gradient from the cover foot to the lid back is so low and the flat bar deforms less.
- Essential to the invention is the limitation of the insulation to the middle upper part. The entire heat radiation of the working element is thereby only slightly reduced and the cooling effect for the machine is maintained. Sufficient heat can still be dissipated through the uninsulated lower portion of the profile, and the isolated upper portion (spine) does not cool so much, thereby minimizing the temperature gradient and associated deformation.
- the claims 1 to 23 have advantageous developments of the invention to the content.
- Fig. 2 flat bars of the revolving lid

Trützschler carding TC, with feed roller 1, dining table 2, lickers 3a, 3b, 3c, drum 4, pickup 5, skimmer 6, nip rollers 7, 8, Vliesleitelement 9, trimming funnel 10, take-off rollers 11, 12, revolving lid 13 with Deckelumlenkrollen 13a , 13b and flat bars 14, jug 15 and can stock 16.
- M denotes the center point (axis) of the drum 4.
- 4a indicates the clothing and 4b indicates the direction of rotation of the drum 4.
- B is the direction of rotation of the traveling lid 13 in the carding position and C is the return transport direction of the flat bars 14, with 30 ', 30 "being functional elements and 13a and 13b being lid deflecting rollers
- the arrow A indicates the working direction.
- a Einstellbogen 17 (flexible bend) is present, which is integrally integrated in the associated side plate 19.
- the setting sheet 17 has a convex outer surface 17a and a lower side 17b.
- the concave inner surface 20b rests on the convex outer surface 17a and is able to slide thereon in the direction of the arrows D, E.
- Each flat bar 14 consists of a back portion 14a and a lid foot 14b.
- Each flat bar 14 has a respective cover head comprising two steel pins 14 ⁇ 14 2 at its two ends.
- a clothing strip 24 with a clothing 18 is attached to the lower surface 14 g of the cover foot 14 b.
- the top circle of flat covers 18 denotes.
- the tip circle of the drum set 4a is designated.
- the distance (carding gap) between the tip circle 21 and the tip circle 22 is denoted by a and is z.
- the distance between the outer convex surface 20a and the tip circle 22 is denoted by b, and the distance between the outer convex surface 20a and the tip circle 21 is indicated by c
- the radius of the convex outer surface 20a is r 3 and radii ⁇ and ⁇ 3 intersect at the center M of the drum 4.
- the side plate is denoted by 19.
- the flat bars 14 are hollow extruded profiles made of, for example, aluminum with an internal cavity 14c.
- the back part 14 a is equipped on its outwardly facing surface with a heat insulation in the form of an insulating coating 25.
- the foot part 14b facing the drum 4 receives operating heat, and the back part 14a facing away from the drum 4 is in communication with the ambient air.
- the heat insulation 25 is present in the upper region i of the back part 14a; the upper region i of the back part 14a comprises the upper cover wall 14 '"and in each case a part 14i, 14 2 of the two longitudinal side walls 14', 14 '' of the back part 14a.
- the flat bar 14 made of aluminum is heated on one side by the carding work and supplies the heat via a surface to the environment. Due to the one-sided heating creates a temperature gradient between the cover foot 14b (working side) and cover back 14a (top). This temperature gradient in itself leads to a disadvantageous deformation of the flat bar 14.
- the flat bar 14 is insulated according to the invention in the upper area i. The insulation is present in the form of a coating 25. The heat transfer via convection to the environment is thereby essentially preserved and is reduced only in a small area i on the lid spine 14 a in order to keep it higher in temperature.
- the temperature gradient from the lid foot 14b to the lid spine 14a is thereby reduced, and the flat bar 14 deforms less. It is essential to limit the insulation to the upper part i (eg 1/3 of the profile height). The entire heat radiation of the flat bar 14 is thereby only slightly reduced, and the cooling effect for the machine is maintained. Sufficient heat can still be dissipated through the uninsulated lower portion k of the profile, and the insulated upper portion i (of the back portion 14a) does not cool so much, thereby minimizing the temperature gradient and associated deformation.
- the cap 26 is arranged in the upper region i of the back part 14a and in the example by two latching connections 27a, 27b in the two side walls 14 ', 14 "attached.
- the thermal insulation may be realized (not shown) by a heat-insulating thin paint, similar to a paint. Due to the thin wall thickness f, the distance between the upper regions of the back parts 14a of two adjacent flat bars 14 in the areas of the two lid deflection rollers 13a, 13b (see FIG.
- Fig. 5 is a perspective view of a flat bar 14 with heat insulation 25 shown in FIG. 3.
- the thermal insulation 25 is suitably unitary and comprises two longitudinal portions 25i and 25 2 along the outer surfaces of the upper portion i of the side walls 14 ', 14 "and a longitudinal portion 25 3 along the outer surface of the top wall 14 1 ", respectively over the entire Length I (see Fig. 6) of the flat bar 14 over the working width of the machine.
- 6 shows a front view of a flat bar 14 with the thermal insulation 25 according to the invention. In the left half a sectional view through the flat bar 14 is shown, in the right half a view from the outside onto the flat bar 14.
- the thermal insulation can be made of styrofoam or the like. consist. In the embodiment of FIG.
- the heat insulation 25 in addition to the lateral parts 25 ⁇ 25 2 and the cover part 25 3 still two parts 25 4 , 25 5 covering the upper region of each of the two end faces of the flat bar 14.
- the heat insulation 25 may consist of thin heat-insulating plates.
- the wall thickness of the parts 25i to 25 5 is chosen such that a vote between the higher heat radiation in the lower region k and the lower heat radiation in the upper region i is such that an undesirable deformation of the flat bar 14 is greatly reduced or avoided.
