Abstract: A stator coil lacing machine includes a carriage pivotably connected to a frame. The carriage supports a needle assembly and cord guide assembly. The needle assembly includes a needle, a needle rotation actuator that rotates the needle about its longitudinal axis, and a needle translation actuator that moves the needle along its longitudinal axis. The cord guide assembly includes a cord guide shaft, a cord guide wag actuator that rotates the cord guide shaft about its longitudinal axis, and a cord guide lift actuator that rotates the cord guide shaft about an axis transverse to its longitudinal axis. A carriage actuator pivots the carriage relative to the frame. The carriage actuator, the needle rotation actuator, the needle translation actuator, the cord guide wag actuator, and the cord guide lift actuator cooperate in a manner that results in lacing of the stator coil.

Abstract: Method and device for continuous production of three dimensional fabrics (50) made up of two or more external layers (51,52) of fabric connected to each other using thread strands (53) starting from separate pieces of fabric, overlapping and joining them and proceeding to sewing using strands (53), said sewing using strands (53) being performed using two pieces of fabric lying and sliding on the opposite faces of a spacer comb-like structure (6), that determines the length of the thread strands (53).

Abstract: A method and a corresponding apparatus provide for both the automatic lacing of a toroidal coil of a stator of a dynamo-electric machine, and the knotting of the end lacing terminal of the lacing cord, by using the same needle and the same thread-guide tube. The apparatus for lacing and knotting comprises an automatic control system that, accomplished the whole lacing operation on the coil, stops the rotation movement of the stator and drives the lacing needle according to a sequence of movements in order to form a plurality of linked rings closed one on the other for obtaining a closing chain on said end lacing terminal. A particular cutting system allows not generating scrap, i.e. undesired cord portions, accelerating the production process and increasing the system reliability.
