Abstract: A device for applying a knot-shaped binding onto the end of a flexible tubular packing, particularly a pork-butchery article, characterized in that it comprises: a hollow mandrel for receiving the narrowed end of the packing, said mandrel being adapted for receiving on its cylindrical outer peripheral surface a previously prepared knot-shaped binding; a sliding push-piece adapted for sliding the binding over the mandrel for ejecting it therefrom and transferring it onto the narrowed end portion of the packing protruding from the mandrel; and suction means for the narrowed free end through the mandrel in order to stretch it axially during the application of the knot.

Abstract: The invention relates to the butchery industry.The machine comprises notably: a vertical splitting carrier mobile along a first column, a mobile horizontal carrier on the splitting vertical carrier, a splitting blade carried by the horizontal carrier, a resilient dorsal guide mobile on a second column, two horizontal arms for encompassing the animal to be slit, rigidly connected to the horizontal carrier and adapted for being connected to the dorsal carrier, and inner guiding means of the spine of the animal to be split, connected to the horizontal carrier.The invention is applicable to the splitting of butchery animals, notably pigs.

Abstract: The suspension device for a power-driven handtool such as a humane killer comprises a yoke having two arms pivotally mounted on two pivots whose common horizontal geometrical axis passes substantially through the center of gravity of the handtool unit. The apex of the yoke is constituted by a bow having the shape of a circular arc whose center is located at the center of gravity of the handtool. Said bow is supported by and capable of traveling on a roller which is freely rotatable on a spindle supported by two arms of a shackle, the central portion of which is attached to a suspension cable.

Abstract: The installation comprises substantially: a chopper for breaking up raw bones with meat still attached to them, an extraction tank containing an alcaline solution with a pH of the order of 10 to 12 for retaining the proteins, a precipitation tank for the proteins by supplying an acid solution bringing back the pH of the liquid phase to a value of the order of 6, and a separation device for the proteins using physical means such as centrifugation, filtration or decantation means.

Abstract: The pistol is so designed that the valve for controlling the forward stroke of the piston is applied directly against the open rear cylinder end which is surrounded by an annular chamber, the chamber being also open at the rear end and in communication with the inlet for connecting-up with the compressed air supply.

Abstract: In a drawing device for sliver comprising two endless moving elements having cooperating working runs between which the sliver passes, at least one of the elements is constituted by a plurality of bars extending between a pair of parallel carriers (e.g. chains) and each bar has a convexly curved outer working surface from which penetration members, (e.g. needles) extend.

Abstract: A textile drawing machine has interchangeable drawing heads mounted between the feed rollers and the drawing rollers, to enable it to treat different types of textile fibres. The heads are readily replaceable in a frame of the machine and have support and drive members engaging support and drive members on the frame.

Abstract: The control system is constituted by a succession of elongate parallel control elements, made of elastomer, which extend in directions transverse to the direction of the path of the fibres to be controlled and which each have a work face and an opposite face provided with at least one longitudinal fixing rib engaged in a longitudinal slit of a tubular support part and terminated by a retention head in the said tubular support part, the drawing device including means for guiding, driving and orientating all the aforesaid tubular support parts, to ensure the displacement of the said control elements for the fibres while abutting against the other control system of the drawing device.

Abstract: In a textile winding machine each of a pair of arms is connected at one end to a first wheel and supports a bobbin at the other end in a winding position with the bobbin resting against a driving roller. An endless band, such as a chain, extends around and engages both the first wheel and a second wheel and also passes around a tension roller. The second wheel is connected to a motor for being selectively driven in each of two directions and for driving the first wheel via the endless band. When not driving the second wheel, the motor blocks rotation of the wheels. The tension roller is positioned by the action of tension control means which has an active and an inactive position. The tension control means includes a shoe abutting against a bladder adapted to be connected selectively to a source of compressed air and to a discharge.

Abstract: The body of the flyer provides two identical limbs and is formed as a single hollow piece and in that the roving guide is constituted by a tube housed inside the corresponding limb and extending on the one hand into the upper part of the hollow shaft and on the other hand, into the corresponding arm.

Abstract: A removable fixing system for the needle bars on chain gills, for supporting and driving the bars, in which each bar is pivotally connected, by its two ends on two chains, and has, at one of its ends, a bent extension the free end of which is engaged in a fixed cam groove the configuration of which determines the orientation of the bar at every point on its path. Each bar is mounted for pivoting, by its two ends, respectively adjacent the inner lateral face of one of the two chains and adjacent the external lateral face of the other of the chains, the pivotal connections between each of the two members constituted by each bar and the corresponding chain each being provided by a respective pivot mounted in overhung manner on one of these two members, in a direction transverse to the direction of the chain, and engaged in a corresponding bore of the other member, while locking means ensure axial positioning of the bar on its pivots.

Abstract: In an automatic textile winding machine comprising a driving cylinder on which rests a slubbing bobbin for being driven thereby, a device for automatically forming an initial bight of a roving around the slubbing bobbin at the commencement of winding comprises a suction nozzle for receiving the leading end of the roving emerging from the nip between the driving cylinder and the bobbin and a reciprocating bight-forming finger which, in moving between a rest position and an operative position, engages the roving extending between said nip and said suction nozzle, and lays it around the bobbin, an air jet carried by the finger then serving to blow the leading end of the roving into the nip between the bobbin and the driving cylinder again.
