Patent ES-368189-A1 (ES)
Title: Yarn assembly apparatus for false twisting yarn
IPC: D02G1/02
Filed: 1969-05-29
Abstract: In yarn treatment comprising separating a two-ply multi-filament yarn into its constituent plies, resistance to the upstream movement of the twist is imposed at a plurality of upstream points, whereby the degree of twist is progressively decreased from full twist at the most downstream of said points to substantially zero at the most upstream of said points. As described, said treatment relates to yarn crimping as described in Specification 1187532, in which two multi-filament yarns 12, 13, Fig. 5, pass in substantially flat, untwisted formation through a first groove 31 formed in a heated body 30, the twist, pre-imparted to the yarns, develops progressively in stages as the yarns engage successive points on a series of rollers, pins or guides, the twisted yarn 18 passes through a second groove 32 in body 30, the heated yarn is cooled to set the twist, and the constituent crimped yarns are then separated and are wound on respective take-up rollers. In Fig. 5, the untwisted yarns engage a point 294 on a fixed, larged-diameter pin 94, whereafter the twist begins to develop. The yarns then pass around a small-diameter pin 95 adjustably fixed in a slot 96, and finally engage pin 94 at a point 194 diametrically opposite point 294, whereafter the fully-twisted yarn passes to groove 32. In Fig. 3 the untwisted yarns pass downwards through a crotch between an upper freely-journalled roller 81 and a lower freely-journalled roller 82 disposed at right angles to roller 81, and ascend through the opposed crotch between the rollers. Twisting commences at the first point of contact 187 on roller 81, and is completed after the final and diametrically opposite point of contact 184 on roller 81. In Fig. 7, the yarns pass in succession through a guide 108, over a tension wheel 107, through a guide 106, and around a pair of pins 101, 102 carried in diametrical opposition by a pivotal disc 103 secured in adjusted angular position by a thumb nut 105, the yarns changing in direction after each point of engagement.

Title: Terminal applicator for terminals in strip form
IPC: B21F15/00
Filed: 1969-06-13
Abstract: Apparatus for crimping electrical connectors 14 to the ends of wires, each connector, prior to crimping, being secured to a carrier belt 2, comprises a pair of crimping dies 186, 188 and 176, 178 relatively movable from a first open position to a second closed crimping position, means 74 for feeding the carrier belt 2 intermittently along a predetermined path to position successive leading connectors secured to the belt 2 between the dies when in their first open position, and means for moving the carrier belt laterally of the feed path when the dies are in their second closed crimping position after crimping the leading connector to a wire end, to separate the crimped connector 10 from the carrier belt 2. A feed support block 72 is slidably mounted on a fixed block 160 and is moved to the right as seen in Fig. 5 by means of a connecting rod 148 which is pivotally mounted between ears 144 on a bracket 146 and which extends through an opening in a frame section 24. The right hand end of the connecting rod 148 is pivotally connected at 150 to a lever 152 which extends upwardly and is pivoted to a bracket 153 fixed to the frame. The upper end of the lever 152 has a cam roller 154 which is engaged by a cam plate 156 mounted on the periphery of an eccentric plate 48 secured to a shaft 50. Thus during each complete revolution of the shaft 50, the cam plate 156 will cause, via the lever 152 and connecting rod 148, the feed mechanism support block 72 to move to the right as seen in Fig. 5. A retaining plate 138 is mounted on the support block 72 and is also moved to the right. In operation, the stripped end 16 of a wire is inserted into the terminal 10 and a clutch 52 engaged to drive plate 48 through a single revolution. During the initial portion of the stroke, the ram 32 moves relatively downwards until lost motion between the ram and a die holding block 192 is taken out. Thereafter the ram 32 moves a further portion of its downward stroke to crimp the terminal 10 on to the wire. During this interval, and while the crimped terminal is being held between the dies, the connecting rod 148 is moved to the right as described above thus pulling the belt 2 away from the terminal 10. The block 72 then returns to its starting position and the ram 32 moves upwardly. An ejector arm 228 then ejects the completed terminal from the crimping zone and the belt feed mechanism is actuated by connecting rod 104 to advance the belt 2 and position an uncrimped terminal between the dies. During the final portion of the cycle, the ram descends partially until the dies surround the uncrimped terminal.
