Abstract A device for transferring the bobbin of a braiding machine between two adjacent flyer wheels of the type in which a double gripper arm is provided for retaining the bobbin, which double gripper arm has retaining claws which engage behind projections arranged on each of the flyer wheels and in which the longitudinal axis of which gripper arm extends through the axis of the bobbin, in which the surfaces of the retaining claws which engage behind the projections are curved to form a radius which corresponds to the radius of turn of these surfaces about the longitudinal axis of the bobbin, the double gripper arm being rotatable relative to the flyer wheel carrying the bobbin, such that one retaining claw engages with one projection, the rotation effecting the locking or unlocking being controllable such that the transfer region extends across a specific region of the path in advance and after the point of transfer with a uniformly accelerated change in the speed of rotation from the speed of rotation of the transferring flyer wheel to the speed of rotation of the receiving flyer wheel.
A device for transferring a bobbin mounted on a spindle of a braiding machine between two adjacent flyer wheels comprising; at least one projection disposed on each of said flyer wheels, a double gripper arm for retaining the bobbin, said double gripper arm having retaining claws which engage behind said projections on each of said flyer wheels, the longitudinal axis of said gripper arm extending through the axis of said bobbin, said retaining claws having curved edge surfaces forming a radius corresponding to the radius of the turn of the surfaces about the longitudinal axes of the bobbin, the double gripper arm being rotatable relative to the flyer wheel carrying the bobbin so that one retaining claw engages with one projection for locking and unlocking the flyer wheel such that the transfer region extends across a specific region of the path in advance and after the point of transfer with uniformly accelerated change in the speed of rotation, from the speed of rotation of the transferring flyer wheel to the speed of rotation of the receiving flyer wheel.

A device for transferring a bobbin mounted on a spindle of a braiding machine between two adjacent flyer wheels comprising; at least one projection disposed on each of said flyer wheels, a double gripper arm for retaining the bobbin, said double gripper arm having retaining claws which engage behind said projections on each of said flyer wheels, the longitudinal axis of said gripper arm extending through the axis of said bobbin, said retaining claws having curved edge surfaces forming a radius corresponding to the radius of the turn of the surfaces about the longitudinal axes of the bobbin, the double gripper arm being rotatable relative to the flyer wheel carrying the bobbin so that one retaining claw engages with one projection for locking and unlocking the flyer wheel such that the transfer region extends across a specific region of the path in advance and after the point of transfer with uniformly accelerated change in the speed of rotation, from the speed of rotation of the transferring flyer wheel to the speed of rotation of the receiving flyer wheel.
Claim 3
Dependent Claim
63 words
The device as recited in claim 1 additionally comprising a guideway for controlling the rotation effecting locking and unlocking, a guide piece being movable transversely to its direction of movement relative to the bobbin spindle, the rotation of the bobbin spindle being produced by said guide piece connected thereto, and two followers rotatably mounted for sliding one behind the other in the guideway.
Claim 4
Dependent Claim
49 words
The device as recited in claim 2, wherein one said followers sliding in said guideway produces a rotary movement of the bobbin spindle, wherein the shuttle runs in the guideway deviating from the bobbin path mounted at the end point of a rotary arm connected to the bobbin spindle.
Claim 5
Dependent Claim
36 words
The device as recited in claim 1, wherein two spaced double-gripper arms are disposed parallel with respect to each other on the bobbin spindle, and additional set of flyer wheels spaced from said original flyer wheels.
