Definitions

  • the yard loom is distinguished from other looms by a mechanism, mounted next to the loom, and called “device for moving yards” or “yard device”. This mechanism introduced respectively removes rods from the fabric.
  • the velvet-pinned fabrics consist of a solid base fabric, executed either in satin or in linen. On the upper side of the fabric, a relief is obtained (produced in the formation of the crowd) by giving larger steps to certain threads, called pile threads.
  • yards are introduced into the opening of the step, between the upper layer of the base step and the raised pile threads.
  • the yards After weaving a few steps, the yards will be removed one by one from the fabric.
  • the loops thus formed will be permanently tightened by the structure of the armor. If the yards are provided with a small knife, we obtain velvet-cut.
  • the invention relates to a method which makes it possible to rotate the looms more quickly while retaining the quality of the fabric.
  • the loom must be equipped with two or more yards movement devices, which are coordinated so that several yards can be removed from the fabric at the same time (instead of one after the other, always separately).
  • device for the movement of yards or “device with yards” means a device, which can introduce into the fabric, respectively remove from the fabric, only one yard at a time. Two or more of these devices can obviously be constructed as an indivisible unit (most often mechanically or electro-mechanically).
  • the insertion of the yards is done as with the conventional yard looms.
  • Figure 1 (Diagram of movements) clearly shows us the times available for various movements (constant speed of the trade).
  • the horizontal axis (T) shows the course of time (divided into periods from Pl to P8).
  • the sinusoid gives the schematic representation of the movement of the leaf.
  • the tangent points with the axis T give the moments with closed leaf (Ll); the upper points give the moments with fully open leaf (L2).
  • this unit of time is represented by P.
  • the devices for moving the yards can be mounted either together on one side of the loom, or separately on both sides of the loom.
  • the basic trade must have the more solid structure and the possibility of reaching high speeds for more or less heavy fabrics, while keeping its stability and reliability.
  • the devices for moving the yards which already exist on the market, can be used (possibly an adapted and / or more refined version), provided that they allow higher insertion speeds.
  • This last condition is also essential when planning a new yard insertion device.
  • the coordination of the yard devices can be carried out completely mechanically, electro-mechanically or even by electronic control (possibly with microprocessor).
  • a recorder is mounted on the crankshaft to control its position. It controls the main counters by an absolute system: for each position of the crankshaft there is always a constant and equal value. Two recorders on each of the yard devices also give (separately) a signal of their position.
  • the meters and comparators are coordinated by a microprocessor, or also by a control module with memory (EPROM, PROM, ROM, etc ).
  • the pulse of the regulating clock, coming from the crankshaft, and the two signals of the recorders of the yards devices are compared mathematically by the microprocessor (or the control module), and the command is transmitted to the servo-motors.
  • the program containing the mathematical reports makes it possible to reach the necessary movement curves.
