Definitions
- the present invention relates to an apparatus for producing toweling in a circular knitting machine.
- Some machines obviate the drawbacks described above by placing pushers between the needles of the cylinder so that they are laterally adjacent to the ground sinkers, replace the sinkers provided with an additional beak, are actuated parallel to the needles, and have saddle-shaped tops that form the casting-off surface for the loops.
- the needle sliding seats are formed on the outer surface of the cylinder (as in machines that do not produce toweling) and the pusher sliding seats are formed on the internal surface of the cylinder: the actuation and selection of the pushers, however, is complicated as it is necessary to act on the internal surface of the cylinder, which cannot be accessed easily and is a confined space that is accordingly unsuitable for mounting complicated actuation devices.
- the technical aim of the present invention is to obviate the above mentioned drawbacks, that it so say to provide an apparatus for producing toweling in a circular knitting machine which acts by means of pushers that are not mounted inside the cylinder so that they can be actuated easily with low-cost devices that can be installed without space problems.
- an object of the present invention is to achieve said aim with a structure that is simple, relatively easy to produce in practice, safe in use, effective in operation, and relatively cheap.
- the reference numeral 1 generally designates an apparatus for producing toweling in a circular knitting machine according to the invention.
- the apparatus 1 comprises a cylinder 2 in which the axis is referenced by A; said cylinder has, on its outer surface, multiple radial and longitudinal seats 3 for guiding the needles 4; said seats are distributed with a constant spacing, and regions Z having a certain width remain between them; it is stressed that the invention is preferably applied to circular machines, in which the needles are somewhat spaced from each other.
- Respective longitudinal slots 5 for guiding pushers 6 are formed preferably at the centerline of the regions Z in the outer surface of the cylinder 2.
- Said pushers 6 have, at their top, a beak 7 which is substantially saddle-shaped and have, at their base, a heel 8 which is folded towards the outside of the cylinder; the heels 8 can have different heights, as shown in the figure by the indices a, b, and c, and can be actuated by three different sets of cams.
- the stems 9 of the needles 4 have, in their upper part, hooks 10 and tabs 11 and, in their lower part, respective heels 12; said heels 12 can have different heights, referenced in the figures with the indices a, b, and c, and can be actuated by different sets of cams located at a different level with respect to the cam sets of the pushers.
- the stems 9 are longer than the stems 13 of the pushers, and the cams of the pushers are arranged above the cams of the needles: this solution allows to interrupt the millings for the pushers before reaching the working area of the heels of the needles and thus avoids weakening the cylinder in this region.
- the cams 14 and 15, respectively for lifting and lowering the heels of the needles, and the cams 16 and 17, respectively for lifting and lowering the heels of the pushers, are mounted on the outside of the cylinder 2.
- the cams 17 for lowering the heels of the pushers have rotating sectors 18 which allow to actuate the heels 8 in both of the machine rotational directions.
- the operation of the apparatus according to the invention is analogous to the operation of similar devices with pushers mounted inside the cylinder, but has the advantage that is allows to mount the heel actuation cams on the outside, without bulk problems: in practice, while one needle descends, the corresponding pusher is lifted, and the saddle-shaped beak 7 raises the loop thread from the ground thread and keeps it raised until the ground stitch and the toweling loops have formed: after forming the stitch, the pusher is lowered below the level of the sinkers to release the stitch and allow the sinker to cast it off.
- the apparatus for producing toweling according to the present invention is susceptible of numerous modifications and variations, all of which are within the scope of the inventive concept.
