Definitions

the present invention relates to a pusher for transferring stitches in a circular hosiery knitting machine.
the aim of the present invention is to provide a pusher which overcomes the drawbacks of the prior art.
An object of the invention is to provide a pusher which is simpler and cheaper to manufacture than conventional types of pusher.
Another object of the invention is to provide a pusher which is significantly less likely to break the yarns.
a pusher for transferring stitches in a circular hosiery knitting machine comprising a shank provided with a lower edge heel, and an active upper portion which is suitable to transfer a stitch from one needle to another adjacent needle
said pusher being characterized in that: said active upper portion comprises a bend which, when viewed from the side, protrudes from the edge of the shank towards which said heel is directed; said bend is formed by a first curved portion, by an intermediate portion and by a rounded step; said intermediate portion is diverted to one side with respect to the plane of said shank, and ends, through said rounded step, with a second substantially straight portion; said second portion is parallel to the plane of the shank but offset with respect it; said second portion ends with a tip through a third oblique portion which is inclined in the opposite direction with respect to said intermediate portion; said tip protrudes, with respect to the plane of the shank, on the opposite side with respect to the one toward which said intermediate portion is
the pusher according to the invention is formed by blanking and bending a flat steel member.
the pusher has a shank 12, which is provided with a lower edge heel 3 and an active upper portion, generally designated by the reference numeral 4.
the active upper portion 4 is constituted by a bend 5 which protrudes from the edge of the shank toward which the heel 3 is directed.
the bend 5 is formed by a first curved portion 6, by an intermediate portion 7 and by a rounded step 8.
the intermediate portion 7 is diverted to one side, respectively to the right (as in Figure 2 ) or to the left, with respect to the plane of the shank 2, and ends, through the rounded step 8, with a second substantially rectilinear portion 9.
the second portion 9 is parallel to the plane of the shank 2 and is offset with respect it.
the second portion 9 ends with a tip 11 through a third oblique portion 10 which is inclined in the opposite direction with respect to the intermediate portion 7.
the tip 11 protrudes, with respect to the plane of the shank 2, on the opposite side with respect to the side towards which the intermediate portion 7 is diverted.
a first bevel 12 is provided, by means of a milling machine, grinding machine or other equipment, or even manually at the second portion 9.
the first bevel 12 allows the pusher 1, in the descending step, not to interfere with the adjacent pusher of the same bend and in an inactive position.
the third oblique portion 10 also has a second bevel 13 which has a similar function to that of the first bevel 12.
Another characteristic of the invention is constituted by a third grinding bevel 14, which is provided at the first curved portion 6 which is suitable to weaken the pusher, because the curved portion 6 is thinner, leaving more space for flexing in the split of the cylinder in which the pusher slides.
the rounded shank 8 forms, together with the second portion 9, a groove 15 which is deep enough and acts as a needle latch opener.
this needle tends to rise and, if the tongue is incorrectly closed, it is opened, lowering by means of the yarn itself of the loop.
a sufficiently deep groove allows to arrange the woven yarn of the loop of knitting in a position which is favorable to act as a needle opener.
induction tempering is performed in order to obtain a tip which is harder than the body of the pusher, which is already tempered but with insufficient hardness.
the induction tempering of the tip allows to extend the average operating life of the pusher.
the pusher according to the present invention is fitted in a circular hosiery knitting machine by interleaving it in a parallel arrangement between two needles 30, in a guiding slot, as shown schematically in Figure 7 .
the pusher is configured so that the tip 11 enters a slot provided in the first needle 30, in a per se known manner, and so that its third oblique portion 10 lies on a plane beyond a second needle 31 arranged on the other side of the pusher.
the second needle 31 can thus pass in a vertical direction between the shank of the pusher and the third oblique portion 10 which is parallel thereto.
the first needle 30 is arranged on one side of the pusher, close to the tip 11, and the second needle 31 is arranged at the other side of the pusher, with the possibility to rise within the bend 5 above the step 8.
the pusher can take, with the tip 11, a stitch from the first needle 30 and divert it toward the second needle 31, retaining it on the step 8 until it is taken by the second needle 31.
the invention achieves the intended aim and objects, having provided an improved pusher which is capable of transferring stitches more effectively and reliably than known types of pusher.
