Abstract: 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.

Abstract: 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.

Abstract: Cutter for cutting yarn in oscillating motion in textile machines, which comprises a first upper mobile cutting element, a second lower fixed cutting element cooperating with the first cutting element in the cutting of yarn, a stem for supporting the first mobile cutting element and a driver for the stem acting to drive the movement of the first mobile cutting element upwards, away from the second fixed cutting element and downwards, towards and against the second fixed cutting element in order to cut the yarn. the stem supports and drives the mobile part and in the raised position forms a part for interception of the yarn in oscillating motion.

Abstract: Device for loading and unloading cops in textile apparatus for winding yarn of the type comprising a cop-holder arm suitable for picking up a cop, supporting it during the yarn winding operation and transferring it at the end of the operation of yarn winding; the device comprises a guide element for the sliding of the cops which extends from the area of pick-up and transfer of the cops and which moves and can be positioned, driven by a suitable drive mechanism, in a first upper position wherein it defines a loading guide for empty cops and in a second lower position wherein it defines a unloading guide for full cops. Elements are also provided for stopping and positioning the empty cops sliding on the loading guide of the empty cops in a suitable position for pick-up by the cop-holder arm of the textile machine.

Abstract: 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.

Abstract: Braking assembly for a reel-holder flange in textile apparatus, comprising a fixed flange connected to the arm for supporting the reel, at least a first and a second braking shoe supported by the fixed flange, each having an external arched lateral face which defines a braking surface for a corresponding internal annular braking band of the reel-holder flange. A drive is provided for driving the braking action which comprise at least a first and a second thrust device provided between the first and second braking shoe at the facing and opposite ends of the braking shoes, with the thrust devices which act on the braking shoes in a direction circumferential to the latter to move them apart one from the other and create a displacement in diverging radial directions of the shoes towards and against the coupling band of the reel-holder flange.

Abstract: A device regulates the tapering of at least one side edge of a package of yarn on a spool in a textile winding apparatus, wherein a reciprocating yarn guide member distributes yarn onto a rotating spool. The device includes a cam having at least a first and a second cam contour, each for driving a respective tapering of the one side edge of the package of yarn and a transmission having an element sliding on the cam for operatively connecting the cam to the yarn guide member. The first and second cam contours are arranged parallel to each other, while the sliding element of the transmission is movable perpendicularly to the first and second contours. Also, there is a device provided for positioning the sliding element of the transmission on a selected contour of the cam contours.

Abstract: A texturing machine has a main framework defining a creel for supporting feed reels of yarn to be processed and a support structure for collection assemblies for textured yarn. The creel and the structure for supporting the yarn collection assemblies are opposite to and distanced one from the other to define an intermediate transit corridor. The texturing machine also has a yarn texturing device supported by the main framework and arranged alongside the creel on its side facing the structure for supporting the collection assemblies.

Abstract: Device for the suction of yarn in textile machines, of the type comprising a conduit, maintained in a vacuum, for suction and transport of the yarn, an external mouth for trapping the yarn connected to said main vacuum conduit, and means of controlling suction of the yarn comprising a cylinder having an internal chamber and a piston for controlling suction moving longitudinally in said chamber of said cylinder and having an internal transverse hole open at its ends for connecting said yarn trapping mouth with said suction conduit.
