Definitions

  • the invention relates to a drive belt for a revolving flat card in combination with a flat rod according to the preamble of claim 1:
  • Such a combination is known for example from DE-A-3907396 (US-4955111). It is there described and shown in particular (Fig. 4), the end of the lid head with a continuous hollow cylindrical Bore and the drive belt with approaches e.g. made of rubber, which in the corresponding holes in the Intervene with the cover heads in a form-fitting manner.
  • the lid head shows teeth with tooth gaps, in which corresponding ones Reach in the teeth of a double toothed belt.
  • the flat bars which are between the flexible bend and the timing belt, it is important that they are guided there sufficiently. However in the area of redirection needs There is a deflection of the flexible sheet so that the flat bars do not fall off the toothed belt.
  • the ends of the flat bars are operated by positive locking between the belt and the lid heads pulled forward over the slide guides and at Return transport on the opposite side of the sliding guides
  • the lid heads are on the side of the revolving lid loosely on the strap and can go unhindered can be removed and replaced from there.
  • the Flat bars fall on the belt even when loose not from the belt because it is with the belt engage in a form-fitting manner. After this Deflection, the flat bars can be easily removed from the toothed belt as they lie loosely on them.
  • the above device has the disadvantage that the flat bars during the deflection and partly on the ascending and falling path of the endless movement loop of the revolving cover mechanically (by special funds provided for this) must be managed. This means an increased, constructive effort.
  • connection system for use with a cover chain is known, wherein a End part of a fastening bolt is provided with a continuous slot, so that two webs are created. Each bridge has an outward approach. The webs are elastic, so that the approaches in one Can snap the slot in the lid head.
  • the system requires a fastener (the bolt) that is self-contained the cover chain must be connected.
  • the arrangement shows compared to the conventional systems (with a Screw instead of bolt) practically no advantages and has not appeared in practice.
  • the invention has for its object to improve the above device such that the Flat bars are guided in a very simple and effective manner, especially in the area of the deflection, and yet the Flat bars are easily connected to the drive belt. This task is accomplished through a combination solved according to the features in the characterizing part of claim 1.
  • the advantages of the present invention are in particular that now no additional mechanical deflection guides more and a simple and practical connection of the flat bars to the drive belt is guaranteed in operation.
  • the flat bars can be easily removed from the drive belt and change.
  • the solution according to the invention is not only available in the known flat bars with cuboid Lid heads, but also, for example, with flat bars that have rod-shaped sliding bolts at their ends are provided, for example according to EP-A-567747.
  • the revolving cover set of a card according to DE-A-3835776 comprises, for example, 106 flat rods 1, of which 41 in the working position, i.e. in contact with the sliding guide.
  • Fig. 1 is a perspective view a part of a flat rod 1 on a so-called flexible sheet 2, which serves as a sliding guide here.
  • the decoration stick 1 has a cavity 3 with a wall 4.
  • the flat bar 1 has two reinforcing ribs 5, in which blind hole-like connecting holes 6 are provided. In these holes 6 sliding bolts 7 are pressed or screwed. On this slide pin 7, the flat bar 1 runs on the flexible sheet 2.
  • the reinforcing ribs 5 are each with an upstanding edge 8 provided so that the set, not shown, can be easily applied to the flat rod 1 by flanging.
  • FIG. 2 Such flat bars can be brought into circulation by drive belts, not shown in FIG. 1.
  • FIG. 2 the left bolt 7a belongs to a first flat rod, the middle two bolts 7b to a second flat bar 1 (indicated by dashed lines) and the right bolt 7c to a third flat bar.
  • the distance between the bolts 7b is fixed, that is to say cannot be changed, and that the Distance, for example, between the bolt 7a and the right bolt 7b depending on the division of the Drive belt 9 is changeable. As such, this distance is not important for the connection system.
  • the about 50 mm wide and 2.5 mm thick drive belt 9 is now in the area of the bolts 7b with a downward, tooth-like projection 10 is provided.
  • This projection has the same curvature laterally towards the bolts 7b like the bolts 7b.
  • a relief slot 11 is provided in the central region of the projection 10. Because the lead 10 is slightly wider in the lower region than the distance between the bolts 7b, this projection 10 is immovable clamped between the two bolts 7b. Nevertheless, the flat rod can be easily detached from the toothed belt 9, since the two cams 12 of the projection 10 are pressed together when the flat rod 1 is pulled away. As well the slide bolts 7b are lightly pressed onto the drive belt 9 when the flat rod is applied. These are the edges of the cams 12 facing the bolts 7b are rounded, so that the projection 10 into the intermediate space snaps easily between the two bolts 7b.
  • Fig. 3 is a second variant of a drive or toothed belt 9.1 in connection with the flat rod after Fig. 1 shown.
  • Two tooth-like projections 10.1 (which are similar to the projection 10 in FIG. 2) embrace the two bolts 7b of the flat bar 1. There is therefore an open space between the two Bolt 7b, which is slightly curved during the deflection on the gear (not shown). This will make the snap connection somewhat looser, but still remains sufficiently stable to secure the flat bars 1 on the toothed belt 9.1 hold.
  • each bolt 7b embraced on both sides by a tooth-like projection 10.2.
  • a tooth-like projection 10.2 Just like in the first possibility according to FIG sides of the protrusions that are executed toward the bolts 7b are partially formed with an identical curvature as the bolts 7b.
  • two such projections 10.2 clamp a bolt 7b of the flat bar 1.
  • Relief slots 11 are again provided in 12 of the projections 10.2, which in this case are made somewhat wider are as in Fig. 2.
  • the relief slots 11 are approximately the same depth as the height (or depth) of the projections 10 or 10.1.
  • FIG. 5 is a fourth possibility of connection between the drive belt 9.3 and the bolt 7b of the Flat bars 1 shown.
  • two different types of projections 10.3 and 10.4 are provided, on the one hand engage between the bolts 7b (projection 10.3) and on the other hand only encompass the left bolt 7b (Tab 10.4).
  • the cuboid end 13 of the flat rod is provided there with a through bore 17, the top and is rounded or chamfered at the bottom.
  • the projection 10.5 is similar to that described with reference to FIGS. 1 to 5 Projections.
  • the cams 12 are rounded off again at the edges pointing outwards, so that a safe "click in and out” is guaranteed.
  • just a blind hole in the cuboid End 13 may be provided, the projection 10.5 shown in the clamped state then always under one is elastic tension, that is, the cams 12 are pressed together at their ends and the slot 11 has a rejuvenated education.
  • the protrusions 10 may be reinforced with glass fibers or the like to make them even more resistant become.
  • FIG. 7 shows the preferred embodiment based on a combination of the first aspect with the second aspect the invention is based.
  • a head piece 36 again comprises an insertion part 41.
  • the head piece 36 is also with a Sliding section 50 provided, the flexible sheet 2 in the working position of the flat bar and when returning one Rail (not shown) is guided along.
  • the sliding section 50 is provided with two attachments 52 and the two Attachments 52 together form a receiving opening 54.
  • the flat bar 31 is compared to the embodiment according to FIG. 8 unchanged - it is therefore only partially (schematically) shown in FIG. 7 and is not used again described with Fig. 7.
  • the drive belt 9 is formed as a toothed belt.
  • the teeth on the "inner surface” 56 of the belt i.e. on the Surface 56, which is directed inwards with respect to the closed path from the circumferential path), works with drive wheels (not shown) together.
  • the projection 10A is received in the receiving opening 54 between the attachments 52.
  • the lead points a slot 11, whereby two "legs" are formed, each of which in the foot part provided with a cam 12 is.
  • the attachments 52 each have an inclined surface 62 in order to better accommodate and hold the cams 12 can.
  • the legs are resiliently compressible for a snap connection to the head part 36 of the flat bar 31 to form.
  • connection that is created between the projection 10A and the attachments 52 is, on the one hand, strong enough to to hold the cover rod on the belt (even if it is no longer guided through the arch 2) and the driving forces to transfer, on the other hand also by an operator without special tools (manually) releasable. Since no additional (loose) elements are necessary, the manufacturing costs and assembly / disassembly can be kept low be carried out efficiently.
  • the material pairing sliding part of the flat rod / sliding guide of the Bow can be optimally adjusted and the production of the body receiving the flat rod can nevertheless be carried out as inexpensively as possible, the strength and weight of this body being chosen optimally can be.
