Definitions

the letter After completion of the core, the letter must be opened in order to insert the coils onto the columns.
This known plant is designed for assembling only cores having rectangular cross section. Furthermore the laminations must be placed on each store in a rigidly predetermined position and are adjacent to each other. The positioning of the laminations, which is done with help of special abutments, is an extremely slow and costly operation.
the frame 20 moves above the assembly plane 32 and the suckers with the picked up laminations move down from the members 24, 26, 28 to lay the laminations thereon.
the frame 22 which is previously moved up to a position corresponding to the store of the yoke patterns and which has been centered on the laminations pack, picks up, by the suckers lowering, the yoke lamination'and brings it at the desired level.
the frame 22 is then moved above the assembly plane 32 along the guides 16 (or above the frame 20, parallel to guides 16), and from the member 30 suitably positioned on the assembly plane 32 the suckers lower and lay down the yoke lamination.
