Patent number: 4725017Abstract: The invention concerns a bench coil winder, comprising a frame for the support of at least one rotary winding spindle, of a tailstock for the spindles, and of at least one movable wireguide for feeding and distributing the wire on the coil being wound. The frame is made in the form of a bedplate (1) and of at least one vertical wall (1A), on which are mounted all the elements forming the machine, and it comprises a body (2) covering all these elements, which is fixed on the bedplate (1). The wireguide (9) is mounted slidable according to the axis Y, perpendicularly to the front wall (2') of the covering body (2), onto a unit movable according to the axes X and Z; on this unit there is fixed a closing lamina (2b), parallel and shortly spaced from the wall (2'), which closes a window (2a) provided in the covering body (2) to let through the wireguide (9).Type: GrantFiled: November 5, 1985Date of Patent: February 16, 1988Assignee: Tekma Kinomat S.p.A.Inventor: Giuseppe Camardella

Patent number: 4722486Abstract: The coil winder is of the type comprising at least two sets of spindles for coil support, rotating about parallel axes and mounted on two opposite surfaces of a bed tilting by 180.degree., this latter rotating about a horizontal axis which is transverse to the axes of the spindles. Two motion transmissions are provided on the tilting bed to independently drive the spindles of a first set and, respectively, the spindles of a second set. While the coils supported by the first set of spindles are being wound, the spindles of the second set are in a waiting position for loading or unloading the coils. According to the invention, an intermediate and/or supplementary working stage is carried out on the coils mounted on the spindles of the second set, taking advantage of the waiting period.Type: GrantFiled: October 22, 1985Date of Patent: February 2, 1988Assignee: Tekma Kinomat S.p.A.Inventor: Giuseppe Camardella

Patent number: 4662573Abstract: The invention relates to a coil winder of the type so-called "in line", wherein the coil supports are carried by a plurality of parallel, rotating spindles, and the wireguides for feeding and distributing the wire to the coils are mounted on a single support bar, adopted to be moved according to the three cartesian axes. According to the invention, the bar is supported at its two ends by two identical support and guide heads, subjected to a single movement control system on the three axes.Type: GrantFiled: April 3, 1985Date of Patent: May 5, 1987Assignee: Tekma Kinomat S.p.A.Inventor: Giuseppe Camardella

Patent number: 4301975Abstract: A device for supplying two separate wires to a wire guide in a coil winding machine of the kind comprising a stationary coil support, a rotating wire guide and two spools for supplying said wires. A first stationary spool is mounted on a support at least partly disposed coaxially to the wire guide axis and the first wire unwound therefrom is guided along said axis, means being provided for guiding the second wire--unwound from the second spool, disposed upstream of the first spool--along a path which runs astride of the first spool and is rotated around it in time with the rotation of the wire guide.Type: GrantFiled: November 20, 1979Date of Patent: November 24, 1981Assignee: Tekma Kinomat S.p.AInventor: Giuseppe Camardella

Patent number: 4294417Abstract: A static wire tensioning device, of the kind comprising a pair of metal brake shoes between which the wire is clamped at a set pressure, the brake shoes being mounted on respective holders through means allowing to adjust the brake shoe surfaces in perfect parallelism relative to one another. The adjustment is obtained by oscillation of at least one of the shoes around two mutually perpendicular axes. At least one shoe has a central bore through which compressed air is supplied to the clamping surfaces of the shoes.Type: GrantFiled: November 20, 1979Date of Patent: October 13, 1981Assignee: Tekma Kinomat S.p.A.Inventor: Giuseppe Camardella

Patent number: 4211913Abstract: The disclosure relates to a method for electrically welding the ends of metal wires to metal terminals of electrical resistors. An arcuate profile electrode is used which is given a rocking movement, during the rocking movement several electrical welding discharges are fed in rapid succession to perform the welding.Type: GrantFiled: January 26, 1978Date of Patent: July 8, 1980Assignee: Tekma Kinomat S.p.A.Inventor: Giuseppe Camardella
-
Patent number: 4207927Abstract: A braiding device for intermittently forming a wire braid from a single wire fed without interruption, of the type in which seizing means seize the wire at an intermediate point along its length and make a movement such as to form a double wire loop combined with a straight portion of the wire to then undergo twisting, has seizing means rigid with a circular sector moved with reciprocating rolling movement along a straight guide, so as to describe a cycloid trajectory.Type: GrantFiled: June 6, 1978Date of Patent: June 17, 1980Assignee: Tekma Kinomat S.p.A.Inventor: Giuseppe Camardella
