Abstract
Abstract Apparatus comprising a plurality of shaped bodies carried on a rotable structure. On the end of each body one edge can be manually placed of a tubular element of textile material forming the leg of a stocking. During the rotation of said structure, each body having said element hanging therefrom, is positioned in front of and adjacent to the free end of a mounting tube in a semiautomatic sewing machine. At this position an elongated rod is automatically operated, such a rod being provided with a hook member separating the edge of the tubular element from the shaped body, overturning and transferring it onto the end of the pounting tube and causing it to slide along the tube, where it is caught by the gripping members the sewing machine is fitted with, the machine then providing for sewing the other end of the tubular element forming the tip of a stocking.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
230 words
An apparatus for loading tubular elements of textile material on mounting tubes in semiautomatic sewing machines for sewing one end thereof to provide finished stockings, the apparatus comprising a rotatable structure a plurality of shaped bodies carried on said rotable structure and spaced apart from one another for carrying said tubular elemens of textile material, said rotable structure having projecting from one face thereof an end of each body which on its outer surface has at least one groove parallel to the pivot axis of the rotable structure, said end of each body having a perimeter substantially as long as said end of the textile tubular elements, a device juxtaposed to said structure comprising at least one axially movable elongated rod, the free end of which when at rest in the inoperative position is clear of the path for the shaped bodies, the device including a control member causing an axial reciprocation of said rod bringing it to graze or touch lightly and then go beyond the projecting end of that shaped body which is positioned at the zone in front of said rod, a hook integral with the free end of said rod facing the projecting end of the shaped body when positioned at said zone, said hook moving in said groove of the body as the rod moves so as to engage the end of said tubular element.
Claim 2
Independent Claim
230 words
An apparatus for loading tubular elements of textile material on mounting tubes in semiautomatic sewing machines for sewing one end thereof to provide finished stockings, the apparatus comprising a rotatable structure a plurality of shaped bodies carried on said rotable structure and spaced apart from one another for carrying said tubular elemens of textile material, said rotable structure having projecting from one face thereof an end of each body which on its outer surface has at least one groove parallel to the pivot axis of the rotable structure, said end of each body having a perimeter substantially as long as said end of the textile tubular elements, a device juxtaposed to said structure comprising at least one axially movable elongated rod, the free end of which when at rest in the inoperative position is clear of the path for the shaped bodies, the device including a control member causing an axial reciprocation of said rod bringing it to graze or touch lightly and then go beyond the projecting end of that shaped body which is positioned at the zone in front of said rod, a hook integral with the free end of said rod facing the projecting end of the shaped body when positioned at said zone, said hook moving in said groove of the body as the rod moves so as to engage the end of said tubular element.
Claim 3
Dependent Claim
78 words
An apparatus according to claim 1, wherein each of said shaped bodies substantially comprise an internally hollow elongated cylinder, within which a basket means is arranged with perforated side walls and bottom and with a mouth or inlet open at said projecting end of the shaped body, the other end of the body being superimposed in a fixed zone of the body path to the mouth or inlet of a conduit which is connected to a suction pump.
Claim 4
Independent Claim
50 words
An apparatus according to claims 1 or 2, wherein said rod is parallel to and slidable on at least one elongated rigid bar which is integral with said device and clear of the path for said shaped bodies, such a bar extending beyond said projecting end of said shaped bodies.
Claim 5
Dependent Claim
36 words
An apparatus according to claim 1, wherein an annular flange also crossed by the groove passing across the outer surface of the shaped body projects from each of said shaped bodies adjacent said projecting end thereof.
