Definitions

  • the present invention pursues the same aim of the above-mentioned embodiments, considerably simplifies this type of machine by making the functional elements in a confined space more accessible for operation, facilitates their interchangeability and provides better insight in assured stitch formation, thus providing a new concept for a wide range of applications of these widespread circular knitting machines arises.
  • the object of the invention according to claim 1 is to provide a single-circular knitting machine in which the stitching of the needles takes place by the needle back from engaging in the needle gaps holding elements that form a gap to the cylinder bevel, which slip through the newly formed mesh leaves and stops at further advance of the needles, the stitches at the tee edge.
  • the retaining elements in one type are an endless spring ring spiral fixed to the knock-off edge whose turns correspond to the needle pitch and engage the needle gaps from the back of the needle, thereby forming the retaining gap required for the continuously secure stitch formation.
  • the newly formed stitch can first slip through the nip at the start of the penetration of the needles. As the needles continue to advance, the fabric is stopped by the gap at the tee edge.
  • An advantage of this design is that no controllable functional parts, such as e.g. Boards, are necessary, but a coherent spring ring spiral from the back of the needle takes over this task.
  • the fixation of the spring ring spiral above the needle cylinder can be realized by the provided for single-circular knitting machines with blanks carrier ring for the board locks on which are arranged in this case instead of the board locks guide fingers, which passes through this spring ring spiral slidably.
  • the stitch formation is freely accessible from the front.
  • a slit ring is additionally attached to the needle cylinder, formed in the simply structured elements transversely to the needles as a mesh pusher and arranged above the slit ring stationary lifting and lowering parts are individually movable so that after knocking off the newly formed mesh of Sliding pusher pushes it behind the needle head and brings with forward movement of the needles with certainty by stitch retention to the needle back.
  • dense knitted fabric of the lowest mesh heights this is another contribution to production reliability.
  • the mesh pushers exercise a dual function, in which their front part is designed as a retaining lug, which forms the retaining gap by means of a small vertical movement.
  • the combined slide and holding element is formed with the shaft between the slot bottom and its cover formed in the annular slots, that the retaining lugs can perform the small vertical movement, which form the required for the mesh securing gap. This movement causes the approach of the needles, analogous to the tongue movement, the system of thread loops on the holding elements.
  • the various mesh pusher / holder designs can also be used to integrate a wear element in the knock-off edge of the cylinder and to fix it in it.
  • the hitherto complex machine design with blanks has the advantage that when forming and knocking off the stitches, the thread runs over exchangeable blanks and protects the abraded edge against the damaging thread inlet.
  • This can be achieved according to the invention in a simplified manner with a spring wire ring which is received in a recess of the knock-off edge, wherein its seat fixing is secured in phases during the rotation of the cylinder by contact pressure of the retaining lugs.
  • the spring wire ring may have a hard layer against wear.
  • the invention can be used in principle for all single circular knitting machine variants advantageous. It leads to a simplifying, normalization-capable machine structure whose central functional units can be supplied worldwide by a system manufacturer and which relieves the machine-builder himself of this task.
  • the development according to claim 6 describes the possibility of the opening of the holding gap (Sp) automatically thread-controlled and make the same machine controlled the closure.
  • the development according to claim 7 protects the knock-off edge (A) of the needle cylinder (Z) against harmful shrinkage of the thread in the stitch formation.
  • the development according to claim 8 relates to the fixation of the spring ring spiral (12) to the abutment edge (A) of the rotatable needle cylinder (Z), which takes place by means of a above the cylinder (Z) fixedly arranged holding system (H). ( Fig. 3 );
  • the development according to claim 10 describes the possibility of fixing the guide fingers (14) by means of a bracket (16) on the knitting system (S) as a holding system G and to integrate the thread inlet (F) into the needle heads (2) therein ( Figure 8 ).
  • the development according to claim 11 relates to the attachment of the actuating arm (25) for the control of the mesh slide (22) on the knitting system (S).
  • the development according to claim 12 is the connection of various functional elements to a functional unit (E).
  • the development according to claim 13 relates to the summary of the functional parts for the control of the mesh slide (22) in a Segment horraufficient (29).
