摘要： A high speed rigid-type strander includes a main shaft or body mounted for rotation about its longitudinal axis with the core wire advanced through the strander substantially along its axis of rotation. Bobbin supporting members are fixedly mounted externally on the shaft or body for rotation therewith and for mounting the bobbins in positions displaced from the axis of rotation. The bobbins are mounted with their longitudinal axes oriented at substantial angles from the axis of rotation of the shaft or body, and preferably at an angle substantially normal thereto. The bobbins can be mounted to either fly-off the wire in a generally radially outward direction or in a generally radially inward direction with the bobbins stationary about their longitudinal axes. A strander of the above general type is also described which can be used in either a fly-off mode of operation or in a traditional pay-off mode wherein the bobbins rotate about their own axes.

摘要： An actuatable member of a pintle assembly is slidably movable along an axis for movement relative to a reel-carrying cradle support member between reel engaging and disengaging positions. Compression springs are used to urge the actuatable members of the illustrated embodiments toward the reel-engaging positions. Locking devices, which can move between locking and releasing positions, are each arranged to directly cooperate and block the movement of an actuatable member to a disengaging position thereof in the locking position of the locking device. The locking devices may include blocking elements such as rigid displaceable balls or pins, or may include cam arrangements and the like. A fluid pressure system is provided to act at least on the locking devices and release the same when fluid pressure is applied. Advantageously, the fluid pressure system also acts on the actuatable member to move the same to the reel disengaging position upon release of the locking device. The described embodiments provide fail-safe operation during reel engagement independently of the fluid pressure provided by the fluid pressure system.

摘要： A fail-safe locking device for reel support systems is described which is suitable for use with reels such as those used with wire stranders and similar machines. In the embodiments described, a pintle supporting shaft member is normally biased by a spring to an extended position. A safety plunger is provided which has a stepped exterior surface so as to define a recess or step. The safety plunger is normally biased by a spring to a disabling position to urge a blocking member, such as a hardened steel ball or sphere, into the path of movement of an abutment surface of the shaft member to automatically and positively lock the shaft member and the pintle. In the locked condition, the plunger member and, therefore, the pintle, cannot accidentally release the reel. The shaft member and the safety plunger are provided with bearing surfaces against which a fluid medium under pressure may be applied by an operator of the machine to, firstly, move the safety plunger from the disabling to an enabling position to permit the ball or sphere to drop into the recess or notch and, therefore, out of the path of movement of the shaft member abutment surface. Once freed, the plunger member is urged by the fluid medium under pressure to a retracted or releasing position. Two opposing pintle assemblies may be mounted on a cradle typically used in wire stranders, and pneumatic pressure is used by the operator to release the fail-safe locking system to accept or release a reel from the cradle. Electrical means may be used for monitoring the position of the safety plunger and for disabling the machine or issuing an alarm upon movement of the safety plunger to its enabling position and, thereby, permitting the plunger member and pintle to move to a retracted position. The fail-safe locking device is also shown on other reel-supporting systems such as bobbin supporting shafts.
