Abstract: A needle apparatus (70) for making a pinning hole in a composite material comprising a needle (14) having a longitudinal axis, a collar (32) fixed about the needle, a motor (16) having an axis of rotation, and being fixed to the needle such that the needle can be rotated by the motor, the motor and the collar being situated within a motor housing (50), the motor housing having a first bush (34), and a second bush (36), wherein the collar is positioned between the first bush and second bush so as to prevent the needle from moving away from or towards the motor, but allow the needle to rotate freely around its longitudinal axis, wherein each needle apparatus further comprises a linear actuator (40) connected to the motor such that the motor can be moved along the axis of rotation of the motor by the linear actuator.
