Definitions

  • heald-guide structure formed of round tubes, which are at least as long as the healds and which are connected, adjustable both in height and in depth, to the loom side structures and positioned close to the middle point of the stroke of the upper part of the healds, bushes being mounted on the healds - coaxial to said tubes and free to rotate - in proximity of the appropriate conventional separators provided between each heald.
  • the pack of healds is slung on the upper and/or lower side by said tubes through said bushes, thereby obtaining a slidable and reliable guide in any desired zone of the healds.
  • Said guide by no means interferes with any interventions of the operator, in case of break in the warp, and it does not project vertically from the healds, nor does it require any intermediate supports, like the known guides.
  • the removal of the rear part of the heald-guide, for loading and unloading the healds is carried out without operating under the warp line, by loosening simply two bolts and totally freeing the rear part of the pack of healds, and it can be performed by a single person.
  • the heald-guide according to the invention is formed of a first pair of round tubes 1 and 2, slightly longer than the healds 3 and connected at 4 to the side structures 5 of the loom, with possibility to be adjusted in height (through displacements in respect of the structures 5, see fig. 2) and in depth (through displacement along the slots 6 of the structures 5).
  • the two tubes 1 and 2 are positioned close to the middle point of the stroke of the upper part of the healds 3 and carry, near the heald separators 7, bushes 8 and 9 for engaging said separators.
  • Such bushes are mounted coaxial to the tubes 1 and 2, freely rotating, in positions along the length of the tubes which are set, with possibility of adjustment, by pairs of clamps 10 being removably locked onto the tubes 1 and 2.
  • This mounting of the bushes 8 and 9 allows to easily adapt the heald-guide according to the invention to the most varied types of healds and to the different positions on said healds of the separators 7, with which the bushes are designed to engage.
  • Figure 1 shows the presence, together with the upper tubes 1 and 2, of a second pair of lower tubes 11 and 12, substantially identical to the first and carrying similar rotating bushes 13 and 14, held by clamps 10 and engaging the lower separators 15 of the healds 3.
  • the pack of healds 3 is slung both on the upper side and on the lower side by the heald-guides according to the invention.
  • the progress proposed by the invention can also be obtained by using only the upper heald-guide formed of the tubes 1 and 2, and letting the healds be guided on the lower side by a conventional heald-guide.
  • the heald-guide according to the invention engages the healds without any slidings (which are always present in corresponding conventional devices), thanks to the rolling contact with the separators 7 and 15, obtained through the bushes 8, 9 and 13, 14 of the tubes 1, 2 and 11, 12. Furthermore, said heald-guide does not in the least hamper any actions of the operator in the event of breaks in the warp yarn, it does not extend above the healds like all the known heald-guides, nor - like all known heald-guides - does it require any intermediate supports.
  • the removal of the rear part of the heald-guide according to the invention, for loading and unloading the healds can be carried out without having to operate under the warp line - as in all the conventional heald-guides - by. simply loosening the two bolts 16, and freeing at the back the pack of healds 3 by lifting the rear tube 2.
  • This operation can be carried out by a single person, with the obvious advantages which need not be underlined.
