  • Patent number: 11404946
    Abstract: An apparatus for manufacturing a stator includes a supporting member configured to support a stator core, at least one processing jig having a cylindrical part and a plurality of protruding parts, and an operating unit. The operating unit is configured to perform, in a state where each of coil protruding parts is inserted between one circumferentially-adjacent pair of the protruding parts of the processing jig and an axial end face of the stator core is located close to the protruding parts of the processing jig, a first operation and a second operation either simultaneously or alternately. The first operation is an operation of relatively rotating the stator core and the processing jig in a circumferential direction of the stator core. The second operation is an operation of relatively moving the stator core and the processing jig away from each other in an axial direction of the stator core.

  • Patent number: 11277060
    Abstract: An aligning apparatus is provided for aligning coil segments in an annular shape to form an aligned coil. Each of the coil segments has a pair of first and second leg portions. The aligning apparatus includes an outer jig and an inner jig. The outer jig has partitioning members arranged in a radial fashion. The partitioning members are spaced at such intervals as to allow each of the first leg portions of the coil segments to be inserted between one circumferentially-adjacent pair of the partitioning members. The inner jig has hole-forming members arranged radially inside the partitioning members of the outer jig. Each of the hole-forming members has formed therein a hole in which one of the second leg portions of the coil segments is to be inserted. Moreover, the hole-forming members are configured to be rotatable relative to the outer jig in a circumferential direction and radially movable.

  • Patent number: 10308474
    Abstract: A film dispenser for use in unwinding film from coreless film rolls. A first dispenser member is selectively matable with a second dispenser member. The first and second dispenser members can be mated together in at least two angular positions. The position of a radially outward facing surface of the dispenser can be adjusted based on the angular position of the dispenser members so that the dispenser can firmly engage and support film rolls of varying internal dimensions. Each of the dispenser members can have a radially extending support wall. The support walls define complementary interlocking formations. When the dispenser members are mated together, the complementary interlocking formations engage one another to form a rigid connection between the dispenser members. The engaged support walls radially support a central region of the film roll.
