Definitions

  • the invention relates to improvements to apparatuses for unwinding coils of relatively rigid wire, for example "wire rod”, such as those described, in particular, in claims 2 to 9 of French patent 81 14208.
  • the present invention is intended to remedy these drawbacks.
  • the invention is mainly characterized by the fact that the horizontal pressure roller is replaced by a fork with two parallel and horizontal branches arranged symmetrically with respect to the diametral plane of the coil, passing through the main vertical upright, each of the branches, which are kept constantly in contact with the upper turns of the coil having a length at least equal to the outside diameter of the coil and, in any case, sufficient to cover each turn, not only in the vicinity of the upright but also in its diametrically opposite part.
  • each of the branches are preferably of solid or hollow circular section.
  • the ends of each curved branch it is preferable to provide the ends of each curved branch so as to diverge on either side of the vertical plane of symmetry passing through the axis of the coil and the amount.
  • Another characteristic of the invention resides in certain proportions of the branches of the fork; in particular, these are separated by a maximum distance of the order of the internal radius of the coil.
  • the double branch presser system makes it possible to maintain, by one branch, a half turn while the other half of the same turn takes place by sliding on the second branch and vice versa.
  • each branch which diverge on either side of the vertical plane of symmetry which has been mentioned above, makes it possible to facilitate the release of the wires towards the center. This release therefore takes place in the area between the two branches of the pressing fork, which makes it possible to further lengthen the turn pitch and to eliminate all the drawbacks which have been indicated at the beginning of this specification.
  • the coils (2) are held firmly along three external generators spaced about a third in circumference and which correspond to the main vertical upright (10) and the uprights (21, 22) and (23, 24).
  • the essential characteristic of the present invention consists in replacing the horizontal pressure roller (43), provided in patent 81 14208, by a fork (70), (701) with two horizontal branches.
  • the fork (70) has two straight branches (431) and (432), while the fork (701) has two branches with curved ends (433) and (434).
  • the branches (431, 434) are embedded on a crosspiece (71) integral with the slide (44).
  • Each of the branches (431-434) is kept constantly in contact with the upper turns of each coil (2). They have a length at least equal to the outside diameter of the coil (2) so as to sufficiently cover each upper turn of this coil, not only at vicinity of the upright (10), as was the case in patent 81 14208, but also in its diametrically opposite part. However, the length of the branches (431-434) is such that their movement cannot be hindered by the leaves (13-16). In the case of leaves (13, 14) controlled by jacks (58, 59) ( Figure 5), said leaves (13, 14) do not completely surround the coil (2) and the branches (431-434) can be longer than the outside diameter of the coils (2). The amounts are then three in number and arranged according to the vertices of an equilateral triangle.
