Abstract: Machine for producing chenille or yarn chenille, comprising yarn-making means which are arranged according to a plurality of formation axes (a1, . . . , qn), characterized in that the said formation axes are disposed along two opposite fronts (F1, F2) of the machine.

Abstract: Apparatus for driving interweaving threads in a yarn-forming unit of a chenille machine comprising, for each of the two sides of a gauge (1) on which the fuzzy thread is wound and sized, a pair of rollers (3, 30) forming a calender for driving two interweaving threads to be twisted in order to engage the lengths of the fuzzy thread. Of the rollers (3, 30), the upper one (3) of at least one of the two pairs is provided with a plurality of radial channels (31) associated to air-suction device to pull in the lengths of fuzzy threads being cut by a blade (2) towards the respective edge, at least over an arc thereof instantaneously facing the gauge (1) during the rotation of the rollers (3, 30) of the pair.

Abstract: Improved machine for making chenille yarns wherein the draw/counterdraw rollers (1,3) are mounted on a support (10) vertically oscillating in such ways as to move close to and respectively away from the gauge (2), with an arm (11) having a fine-thread screw register (13) and with stoppage of the rollers (1) before they touch the gauge (2). The shaft (12) of the draw/counterdraw rollers (1,3) is interlocked to a translation device able to adjust the axial position thereof. The rotary disk blade (4) for cutting the fuzzy thread is mounted on a shaft (40) whose ends are supported by bearings (41) and is lubricated and adjustable in height. The rotary head (6) for winding the fuzzy thread on the gauge (2) is mounted on a shaft (60) which is fitted on bearings (61) within a support (62) adjustable in height a fine-thread screw register (63). The gauge (2) is mounted on a slide (20) movable on a horizontal guide and whose position is adjustable by a fine-thread screw register (21).

Abstract: Dampener for a bearing arthro-prosthesis made up of a cradle (1) with a base zone of spherical shape to be interposed between the presser, head (3,2) and the cotyle (4) of the prosthesis, which has stepped cross-section, in the meridian plane, with a thin wall (10), a first central step (11) rising from the bottom of the cradle and more circumferential spaced apart steps (12) being parallel to and coaxial with the central step (11) and having lesser height than the first step. In this way, it is possible to obtain, with a non-compressible material, a variable rigidity of the cradle when subjected to loads applied to the prosthesis as well as maximum deformation increment at the lowest values of the load (approx. 100 kg).

Abstract: A device for the production of a boucle type fancy yarn comprises two off-center rotating members engaging, via off-center bearings, a central element which remains stationary. The central element carries a triangular tool having a lower extension flanked by two entraining means. An effect yarn is fed by one of the rotating members in order to form turns around the tool and its extension. A first core yarn, which acts as a binding yarn, is fed along the extension to pass within the turns of the effect yarn, while a second core yarn engages the effect yarn turns from the outside.
