Abstract: The present invention relates to a selecting device to be disposed downstream of a springs forming device of a springs forming machine. The selecting device may include an inlet adapted to receive springs formed in the springs forming device, outlets adapted to eject each of the springs from the selecting device, means for selectively conveying each of the springs entering the selecting device through the inlet towards the outlets, and means to form conduits to connect the inlet to the outlets. The selecting device may include means for generating a depression in at least one of the conduits and means for generating a compressed air flow directly inside the selecting device at one of the conduits.

Abstract: A method is provided for verifying operative parameters of a selecting device of a machine for forming springs, configured for subdividing the springs formed by a spring forming device of a spring forming machine in at least one first group corresponding to springs having dimensional parameters falling into predefined tolerance values, and a second group corresponding to springs having dimensional parameters varying from the predefined tolerance values.

Abstract: The present invention refers to a spring forming device (1) comprising: a system (3) for feeding a wire (4) for forming a helical spring (2); a winding system (7) suitable for winding said wire (4) according to a helical configuration having a predefined diameter (D) extending along a helix development axis (A); one or more pitch tools (11, 13, 9), each suitable for acting on the wire (4) so that it takes on said cylindrical helix configuration with a predefined pitch (p); a system (15) for detecting the actual pitch of the spring forming in device (1) starting from said wire (4); means for detecting the amount (I) of the fed wire; a control unit configured for: —determining the actual length (Leff) of the spring forming in the device starting from the actual amount of the fed wire (I) and actual pitch (peff) detected for portions of the spring, already formed in the device; —determining a reference length (L) as a function of said actual amount (I) of fed wire; —determining an error between said reference le

Abstract: A device for assembling two panels and formed by a male part (1) and a female part (2), designed to be inserted into bores provided in these panels, the female part being constituted by an elastically deformable clip (2) provided with a cap (20). The cap (2) is itself elastically deformable, so as to prevent any play between the panels.

Abstract: The invention concerns a hold-down fastener including a barrel including internal lips cooperating with a screw thread, the lips being directed inwards of the barrel and inclined in a direction of insertion of the screw into the barrel. Each lip includes at least two parts, a first part connected to the barrel and inclined at a first angle relative to the barrel, on the side for inserting the screw, and a second part connected to the first part and inclined at a second angle relative to the barrel, on the side for inserting the screw. The second angle is larger than the first angle and less than 180° to facilitate the insertion of the screw into the barrel, while maintaining the fastener screw-holding power after the screw has been inserted. The invention is useful for fixing in place electric cables, piping systems, and other cylindrical articles.

Abstract: The invention concerns a heat sealing composition including an adhesive framework and a framework forming constituent, the adhesive constituent being a maleic vinyl-anhydride ethylene-acetate polymer or a vinyl ethylene-acetate polymer modified to have epoxy functions and the framework forming constituent being selected from among a block polyether amide, modified or not, and a block polyether ester. The composition is useful for making closure plugs.

Abstract: The invention relates to an obturating stopper plug as well as to a method of manufacture of this stopper plug.The stopper plug for obturating any opening (2) and comprising a bead of heat-fusible adhesive (7) deposited upon the said stopper plug is characterized in that the bead of heat-fusible adhesive (7) comprises:(a) an adhesive mixture,(b) a cross-linking agent,(c) an expansion agent decomposing at a temperature close to the cross-linking temperature of the adhesive mixture (a),(d) additives for working purposes.The invention is applicable to the obturation, for example, of an opening in a plate to be passed into a drying oven for paint.

Abstract: An automatic fastening or closing device operating by moving past a dead point and comprising a base portion to which are pivotally connected arcuate tongues themselves pivotally connected by hinges to lugs and comprising each one an outwards projecting portion to form a bearing point allowing the lugs to assume a position remote from each other, i.e. an open locking position, the device being applicable to the fastening and to the locking in blind relationship of a box-like or channel-shaped part onto any support or member whatsoever.

Abstract: An attachment fitting for the fastening of a part provided with a rod onto a wall, the attachment fitting having the shape of a shank of plastics material comprising a base forming a cup for receiving a washer with claws whereas above the base are provided elastically deformable tongues allowing to clip the shank into the aperture of a wall while positively retaining the washer within the cup of the base, the attachment fitting being applicable in particular to the fastening of a shield onto a metal sheet belonging to the body of an automotive vehicle.

Abstract: An ornamental wheel hub cap adapted to be secured onto the wheel rim of a vehicle through the medium of a resiliently deformable ring split to form two free ends connected together by a spring-like wire allowing the radial deformation of the ring whereas a strap is made into one piece of material or moulded at its two ends integrally with the free ends of the ring so as to exert upon the latter a prestress against the force exerted by the wire spring.

Abstract: An ornamental wheel hub cap to be secured onto a vehicle wheel rim through a resiliently deformable ring split to form two free ends connected by a spring-like wire allowing the radial deformation of the ring whereas a strap may removably mounted between both free ends to exert a prestress onto the ring against the force exerted by the spring wire.

Abstract: A fastening clip device which includes a resiliently deformable U-shaped clip having two legs connected by a base. An arc-shaped tongue originating from one of the legs has a free end which can exit through or co-operate with the edge of an opening. By virtue of this construction, the clip is maintained open before clipping and allowed to close after clipping.

Abstract: A fastening clip device forming a nut in the form of a resiliently deformable U section adapted to be fitted by its legs onto the edge of a panel, and having a member interposed between the legs so as to hold them positively apart prior to their fitting onto the edge of the panel and being movable relatively to the legs so as to be displaceable therebetween under the action of the panel as the legs are passed over the edge surfaces thereof. At the end of the fitting operation, one of the legs is released to allow the U section to resiliently close onto the edge of the panel.

Abstract: The present invention relates to a clamp for securing an element in a recess provided in a support. This clamp has the general shape of a parallelepipedic cup and comprises a base portion applied on the bottom of the recess and two pairs of mutually confronting branches including means for anchoring the cup within the recess and the element within the cup.
