Abstract
A braiding machine having inner and outer tables mounted for counter-rotation about a vertical axis, a stationary, standing rib cam positioned beneath the outer table, a strand guide arm supported on the outer table and having a guide eye that travels in an arcuate path in which all points in the path are equidistant from the strand braid point and connecting and driving elements operably joining the rib cam and the guide eye arm to effect positive arcuate movement of the guide arm.
Claims6
In a braiding machine having inner and outer bobbin arrays spaced circumferentially around inner and outer tables mounted for counter-rotation about a vertical axis, the combination comprising:
- a. means defining a stationary standing rib cam located beneath the outer table;
- b. strand guide means supported on the outer table for pivotal movement about pivot axes which pass through the braid point to provide a strand guide exit point that travels in an arcuate path in which all points contained in the path are equidistant from the braid point;
- and
- c. drive means for effecting positive oscillation of said strand guide means in opposite directions about the pivot axes thereof, said drive means including:
- i. operator means attached to the underside of the outer table having cam follower means depending therefrom into operative contact with each side of said standing rib cam, a portion of said operator means being positively displaced toward and away from the braiding machine vertical axis as the outer table is rotated;
- and
- ii. push rod means operatively connected at one end to said strand guide means and at the other end to that portion of said operator means which is positively displaced, whereby said strand guide means is oscillated.
