Description
TENSIONING DEVICE FOB STOCKINGS This invention relates stocking tensioning device for use with circular knitting Previously proposed devices for tensioning stockings produced by a circular knitting machine an intake conduit which extends downwardly from th needle cylinder and then curves away to form a pneumatic conveying When the stocking fabric during its formation reaches th conveying it tends to be retarded then to be twisted within the length of conduit extending between tensioning and conveyin conduit and the knitting which rotates with the needle This whic is unimportant for conventional becomes particularly difficult to solve when conventional are replaced by a stocking a greater such as knitted tights According to the present there is provided a pneumatic tensioning device for use with a circular stocking knitting comprising a sheath coaxial with and lying below the needle cylinder of machine a rotary duct and coaxial with the the lower end portion of the duct being a suction and discharge conduit communicating with lower end of the rotary perforate a suction tion to the interior the means for applying suctio to suction and discharge means for applying suction to the said suctio and means for selectively activating one of the suction applying means whereby suction is during initial formation of a stocking suction and discharge conduit after the end of the stocking has just the suction and discharge suction is cut off the latter and applied to the connection to the interior of the sheath thereby applying suction to the wall of the perforate duct to retain the stocking on the interior surface of the rotary An embodiment of a tensioning device in accordance with the invention for with a circular knittin will now be by way of wit reference to the accompanying diagrammatic in Figure 1 is a vertical section of the device according to the combined the needle cylinder of a circular Figures 2 and diagrammatically pneumatic circuit unit with an air control in two different Referring now to the the needle cylinder 1 of a knitting machine is in which cylinder is assembled on a stationary structure with which a support underlying the needle is also The support is arranged to hold a forming a part of a fixed casing of the The sheath is and a closure wall is secured across its upper which surrounds a part of a duct whic is narrow and which is combined wit a portion f an open portion aligned with the working zone of the needles of the cylinder gearbox 10 has a casing which is ith the lower end the gearbox casing is formed by two portions 10A and 103 and has therein gea pinion drivable through a coupling and a gear wheel meshing with the pinion which gear wheel is coaxial with the sheath with the duct 9 and funnel portion gear wheel has a large central aperture and is rigid with a duct extending internally the sheath mounted together with the gear wheel 14 on the parts 10 by means of 18 and duct 16 has plurality of appropriately distributed alon the length lying between the 18 and The apertures may have an density in the lower portion of the duct that is in the portion nearer the bearing A connection 22 to the cavity defined by the sheat is also provided he lower bearing The lower of the gear box 10 has an projecting fitting which is aligned with the aperture in the gear wheel and also the tured duc The free end of the fitting is connected to a fixed condui 26 whic away from the device and forms conveyin conduit for the of the diagrammatically a pneumatic circuit unit i combined with conduit 26 and with the connection conduit 26 leads to 28 is The chamber 28 is formed in part by lower the of and an upper screen Suctio is through a conduit to the screen conduit 5 communicates with the connection two conduits and 5 communicate wit a chamber in communicates throug a conduit 58 with a fan unit shutter 42 is mounted the chamber 56 includes a part extending across a diameter of the chamber and an arcuate section Che shutter 42 can be controller through an external lever a tie rod 46 and a rocker arm by a 50A of a conventional program cam controls a rocker arm arranged to door In the position in valve shutter 42 in a position wherein suction is transmitted through the conduit the chamber the conduit the and the conduit illustrates a different position of the valve shutter wherein suction is mitted the conduit 4 the connection the chamber and the conduit In position of the shutter it is possible to shut the conduit to cut off suction both from the conduit 26 and th connection the is At the start of the stocking 22 and an air intake is provided through the conduit When the initial portion of the fabric has reached the fitting 24 and the conduit 26 before irst curve in the conduit the suction applied to conduit 26 is transferred to connection 22 by the system of the Under these suction is continuously applied to duct a a tensioning of the fabric being produced is continuously the suction is also developed through the apertures in the duct 16 and the divided which are produced through these apertures tend to fabric to adhere alon the duct thus preventing of the fabric the conduit As a result a more or less wrinkled or otherwise irregular configuration of the fabric is formed internally the rotary duct 16 which rotates at the speed of the needle cylinder When the knit fabric has needle cylinder the suction is restored to the conduit 26 and the off from the connection Under the knit fabric is entrained pneumatically and the entrainin takes place positively from the end of the because the presence of the end the conduit The initial position in the conduit s thus maintained until end positively enters into the conduit The presence of the perforated duct 16 allows pilin of a length of and avoids the twisting of the since the delivery the initial end of the in the fixed delivery conduit 26 is interrupted at a desired level by a programmed control The stocking is thenpositively extracted and always with the initially formed end remainder The stockings are delivered successively the chamber insufficientOCRQuality
