ABSTRACT:
An improvement in internal cam rotary braiding machines wherein each lower carrier member thereof includes a plurality of oppositely disposed movably mounted and fixedly mounted pulleys used to convey a strand of material from a supply bobbin upwardly to the upper carrier members thereof, the pulleys being arranged to reduce the unwanted stresses which are normally imposed on the strand as it is conveyed upwardly over a deflector member and thence as it drops off the trailing edge of the deflector. Further structural improvements are made with respect to the spindle assembly used for the supply bobbin to reduce the normal movement, or "play," of the spindle assembly components during operation and, hence, to reduce further undesired stresses on the strand. The tension on the movably mounted pulleys can be adjusted to maintain a desired tension on the strand of material during the braiding operation to permit the braiding of very small filamentary materials with little or no breakage thereof during the braiding operation.
