摘要:
A braking device for spindles of textile machines, in which the spindle is caused to rotate by an endless drive belt; the braking device comprises a pivotable brake supporting member provided with a braking pad and a belt-disengaging idle roller. The brake support member is pivotable between a first operative position in which the braking pad and the roller are disengaged from the spindle and respectively from the drive belt, and a second operative position in which the idle roller disengages the belt from the spindle and the braking pad is pressed against the belt-pulley of the spindle; spring means act to maintain the brake support member in both operative positions.

A device for inserting yarn on a yarn-holder cop in winding apparatus, of the type comprising a part for trapping and inserting yarn on the cop moving between a backward rest position and a forward position for insertion of the yarn on the yarn-holder cop. For cutting a lower branch of yarn, there is provided a cutting part having a first and a second cutting element moving one in respect of the other for cutting the yarn. Structure is provided for trapping the lower branch of the yarn and for driving the cutting part which can be actuated and are actuated mechanically by the yarn insertion part. The yarn cutting part is arranged near the yarn-holder cop at the point of insertion of the yarn by the yarn insertion part.

A control apparatus for yarn twisting machines includes a control panel provided with electrical devices for setting the speed of the units for feeding, taking up and winding up of the yarn. The electrical devices are provided on one side of a control panel and are aligned with respective digital displays, and with relative symbols indicative of the arrangement of the various working units of the twisting machine. A main control device enables all of the working units to be set simultaneously, while leaving the relative speed ratios unchanged.
摘要:
A winding machine having yarn guides for guiding the yarn on a bobbin, mobile supports for supporting each yarn guide, and a driver for imparting reciprocating backward and forward motion to the yarn guides. The driver includes a continuous linear element to which supports for the yarn guides are attached, and a drive rod having a longitudinal axis and which moves reciprocatingly in the direction of the axis. The drive rod is attached to the continuous linear element and thereby drives the yarn guides connected thereto in a reciprocating motion to distribute the yarn on the respective bobbin.
摘要:
A texturing textile machine has at least one heating oven for the yarn (20) and downstream thereof a relevant texturing or false-twist spindle (22). There is provided between the yarn heating oven (20) and the relevant texturing spindle (22) yarn cooling elements (28,30) for the forced cooling of the yarn.

Apparatus for insulating air-conditioning and soundproofing a work area of a textile machine includes a tubular cover arranged around the work area fitted with hatches for inspecting this area, an air-conditioning unit; which takes atmospheric air from the working environment of the machine and, after having conditioned it in a desired manner, feeds it inside the aforementioned tubular cover, and a manifold device for discharging "exhausted" conditioned air, coming from the inside of the tubular cover towards the outside of the working environment of the textile machine itself.
摘要:
A yarn winding machine comprising a plurality of rotatable vertical spindles arranged in a longitudinal alignment on a support frame; single yarn guide members for the yarn to be wound on the bobbin placed on each spindle, are provided on mobile support members operatively connected to respective reciprocating drive members.
摘要:
Crochet knitting machine with weft bar adjustment and guide assembly. The bars are carried on mobile supports, each one of which comprising a first device for adjusting the position along a vertical axis and, respectively, a second device for adjusting the position of the support along a horizontal axis parallel to the needles of the machine.
摘要:
Feeder apparatus for the automatic insertion of added yarn according to the present invention, of the type suitable for being installed on textile machines provided with at least one support creel for the bobbin of base yarn and automatic change of the spool of combined yarn, comprising at least one first and one second unit for feeding the added yarn, means for directing said added yarn and means for coupling the added yarn with the base yarn to form the combined yarn, characterised in that each unit for feeding the added yarn consists of a reel of added yarn placed on support means in contact with a motorised feed roller, in such a way that each feed unit is provided with its own feed roller and is independent from the others, and relative method.
