Definitions

  • a flexible belt for fitting in a round baling machine of the kind referred to having a width substantially that of the bale forming rollers, having a length such that it can be entrained around a group of such rollers, and a partable join so that it can be fitted without disturbance of said rollers or adaption of the machine.
  • the join is formed with an overlap of the ends of the belt, and these ends may have attached thereto, across the width of the belt, complementary strips of interlocking pile fabric, such as that known as VELCRO (R.T.M.) where the respective piles have hooks and eyes.
  • VELCRO R.T.M.
  • These strips may be adhered to the belt, especially if they are available with a self-adhesive backing. Alterna ⁇ tively, they may be welded. However, as welding can irrevocably flatten the pile and reduce its shear strength, it would be inadvisable to do this over the entire area of each strip. Instead, the welds may be done in a skeleton pattern, for example in a diamond pattern grid. There could also be a combination of adhering and welding.
  • the belt may carry marking and/or be shaped to indicate the manner of fitting and the correct alignment of the respective ends.
  • the belt requires good frictional and abrasion-resis- tant surfaces, one for efficient traction by the rollers and the other for entraining the straw or other material.
  • Polyurethane will serve well for both purposes and it i ⁇ preferred that the belt should have a fabric core with an ether-based polyurethane coated on opposite sides.
  • Figure 1 is a diagrammatic longitudinal vertical section of a baling machine for producing round bales
  • Figure 2 is an enlarged detail of Figure 1
  • Figure 3 is a plan view of part of Figure 2, showing a belt join.
  • the machine of Figure 1 will not be described in detail as the general principles are well known.
  • the bale forming rollers 1 are in a generally cylindrical array to define the bale shape, and the straw is fed in through a gap 2 onto a group of rollers at the bottom of the array. It is these that are particularly critical in entraining the straw and initiating the bale forming process and, as mentioned above, in some circumstances they fail to do this.
  • the problem is substantially alleviated by having a belt 3 around these rollers.
  • the belt is not an endless loop, which would be impossible to fit without quite a bit of dismantling. Instead, as seen in Figure 2, it has overlapping ends which fasten together by strips 4 of interlocking pile fabric extending the width of the belt, which corresponds to the lateral span of the rollers.
  • This belt can be fitted without any adaption of the baling machine, and by one man.
  • the belt ends need to be aligned properly, and to do this there are provided arrow marks 5 and 6 on the exterior, straw engaging surface which come' into conjunction at the trailing edge of the overlap.
  • the direction in which these arrows point indicates the direction in which the belt should move.
  • the arrow 6 will be rather more protected but, as a precaution, the belt may have an indented mark to augment that arrow, or there may be a welded-on triangle of polyurethane, of contrasting colour to the main belt.
  • a pattern of welding the pile fabric strips at the overlap will provide adequate anchorage while incurring minimal damage to the pile as a whole.
  • adhesive could be used, and there could be a combination of the two techniques.
  • solvent is applied to those backs or to the polyurethane belt coating over the regions where the strips are to be attached, the strips are applied and smoothed out so that they adhere by means of the tacky polyurethane, and then welding is carried out.
  • Thi ⁇ solves the problem of keeping the strips accurately in place during welding.

Abstract

Une machine à faire des balles rondes possède deux rouleaux parallèles (1) situés sur un élément cylindrique qui entraîne la paille ou un autre matériau et lui donne la forme d'une balle cylindrique. Une courroie (3) servant à rassembler un groupe de rouleaux de ce type (7) est aussi large que l'écartement latéral des rouleaux et elle possède un joint ouvrant de sorte qu'elle peut être mise en place ou enlevée sans toucher aux rouleaux et sans adapter aucun élément à la machine. Le joint peut être formé par des bandes (4) de tissu à enchevêtrement réciproque fixés et/ou soudés aux extrémités de la courroie (3), il est préférablement réalisé dans un matériau recouvert de polyuréthane, offrant un ajustement presque parfait sur une surface limitée.
