  • ABSTRACT In a shuttleless loom, a length of at least more than one pick of filling is pulled from a supply package located outside the shed continuously and at constant speeds and is partitioned into picks in a coil and advanced continuously toward filling-inserting means, the coil being caused to maintain a given pitch and accumulated on a storage swift. 1n multi-filling, such [30] Foreign Application Priority Data Aug. 9, 1969 Japan..................................44/63209 Nov. 4, 1969 Japan...........
  • '139/122 R storage swifts are disposed in numbers equal to the number of 47/36 fillings to be selected, and each filling is continuously pulled from supply packages at constant speeds compensating for the 139/ 122 R, 127 P; 242/47.l3 use and accumulation of the fillings.
  • the present invention relates to methods of and apparatus for measuring filling and inserting it to the shed in a shuttleless loom, wherein the length of the filling is accurately measured under stable, low tension while the filling is being payed out from a supply package. n release from measuring means the filling is inserted in the shed and after insertion it is relaxed such that the degaradation of quality of fabric due to excessive filling tension at the time of beating up is prevented.
  • the measuring means a plurality of types of filling can be selectively inserted into the shed while they are being measured and accumulated.
  • the filling can be maintained under a consistent, low tension and inserted in the shed accurately and uniformly; since the accumulated filling is not subjected to kinetic friction, the shape deformation of the filling such as fuzzing will not occur; and a wide selective order of filling-inserting'is optionally adopted by a simplified apparatus.
  • the present invention relates to measuring the length of filling and inserting it into the shed.
  • the feature of measuring the length of the filling to be inserted in the shed per pick is not separate from that of filling-inserting, but both are closely correlated.
  • the latter feature follows the former feature, or it can be thought of as the former being in anticipation of the latter.
  • the improvement comprises accumulating it and measuring its length, more particularly providing means of accurately measuring the length of the filling continuously pulled out from a package under a stable low tension.
  • On measurement of the length of the filling it is released from a measuring means and inserted in the shed. Then it is made slack such that it prevents the deterioration of quality of the fabric made thereof as is the l case with excessive filling tension at the time of beating up,
  • the length of the filling to be measured is freely controllable. Further in a selective filling insertion, even when the measured filling is needed to be stored as it is, the accumulation of the filling under constant tention is possible.
  • Another feature of the reference is that a considerable amount of filling can be stored in spirally wound conditions on the swift and the rotation of the swift as well as the unwinding of the filling accompany the interrupted formation of balloon between a place where the filling leaves the swift and a place where the filling is guided to be presented to the filling-inserting means.
  • the filling is not subjected to a sudden impact. Assuming that the filling is intermittently pulled from a supply package instead of the accumulating device, it starts moving or stops with an impact, which causes yarn breakages or injuries.
  • the present invention provides means for determining the length of the filling. This constitutes a big difference over the reference.
  • a plurality of endless belts which continuously run in substantially the same direction at substantially the same speed, form a swift.
  • the outside runs of the endless belts are adapted to be a means for measuring the length of the filling. Filling is spirally wound around the swift and an appropriate amount of the filling is stored. On measuring runs there are positioned measuring guides at regular intervals. Filling equivalent to the amount to be inserted per pick is wound between two guides.
  • the filling is disengaged from the measuring guide at the leading position of the filling per pick just before the insertion and is pulled out to the guide running direction, that is the filling-inserting side.
  • the measuring guides With the use of the measuring guides a plurality of types of fillings can be selectively conducted to the shed. This multifilling operation will be described later in more detail.
  • the present invention has as its object the following:
  • a plurality of measuring guides adapted to have a predetermined interval between them, and over said plurality of measuring runs is spirally wound the filling so that the length of the filling to be inserted in the shed per pick is held between the two guides.
  • the hold of the measuring guide on the filling is released at every pick to pull the filling in the guide travelling direction and insert it into the shed.
  • the freemovemerlt in the running direction of the wound filling is intercepted by said measuring guide. But when, the measuring guide passes through the inside of a filling trip guide disposed near the forward end of the measuring run so as to face the measuring guide, the filling is made to pass through the outside of the filling trip guide, and inserted into the shed after leaving the measuring means.
  • the fillings are continuously pulled ata constant speed from the package situated outside the shed so that the length of fillings inserted into the shed per unit cycle of multifilling operation is supplemented, and at least the length of filling to be insertedjper pick is measured and accumulated individually at the time of insertion so that filling tension during insertion is substantially equally maintained.
