Abstract
Abstract An automatic cell cutting, forming and inserting machine including a turret driven in a step-by-step manner to carry stators from a loading station to a cell inserting station to an unloading station, the stators being positively aligned in the turret and indexed at the inserting station in a step-by-step manner in sequence with a cell cutting and inserting apparatus, the cell cutting and inserting apparatus including a material feed assembly for feeding a strip of cell material through a cutting assembly to a cell forming and inserting assembly. An edge cuffer is positioned in the path of motion of the strip of cell material to form a cuff on each edge of the strip of material. The cell forming and inserting assembly includes a cell carrier positioned to receive said strip of cell material, a cell creaser blade operatively positioned to engage said cell carrier to hold and crease the strip of material prior to cutting, and a cell former to wrap the cut strip around the cell carrier to form the cell. The cell is carried on the cell carrier through a plow which has the same shape as the slots in the stator into a slot in the stator. The indent or crease in the cell on release from the cell carrier biasing the cell outwardly to form a snug fit in the slot.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
128 words
In a cell inserting machine for automatically inserting cells into the slots of a stator, the machine including: a turret vertically mounted for rotary motion on a base, the turret being indexed to move a stator from a loading station to a cell inserting station to an unloading station, the improvement comprising: means for feeding a strip of cell material into said inserting station, means for holding the end of the strip at the inserting station, means for cutting the end of the strip tO a predetermined length, means for forming the cut strip to the shape of a stator slot, a plow for guiding the cell into the slot of said stator, and means for carrying the cell through said plow into a slot in the stator.
Claim 2
Dependent Claim
128 words
In a cell inserting machine for automatically inserting cells into the slots of a stator, the machine including: a turret vertically mounted for rotary motion on a base, the turret being indexed to move a stator from a loading station to a cell inserting station to an unloading station, the improvement comprising: means for feeding a strip of cell material into said inserting station, means for holding the end of the strip at the inserting station, means for cutting the end of the strip tO a predetermined length, means for forming the cut strip to the shape of a stator slot, a plow for guiding the cell into the slot of said stator, and means for carrying the cell through said plow into a slot in the stator.
Claim 3
Dependent Claim
24 words
The machine according to claim 1 wherein said plow includes a slot tapered to a shape substantially similar to the slot in the stator.
Claim 4
Dependent Claim
31 words
The machine according to claim 3 including means for moving said plow into abutting engagement with said stator to align the slot in the plow with the slot in the stator.
Claim 5
Dependent Claim
20 words
The machine according to claim 1 including means for forming cuffs around the edges of said strip of cell material.
Claim 6
Dependent Claim
75 words
The machine according to claim 1 wherein said carrying means includes a cell carrier mounted for movement into the slots of said stator and having an outer shape generally conforming to the shape of the slot in the stator and said forming means includes a forming block having a slot shaped to wrap said cut length of material around said carrier and means for moving said forming block to wrap said strip around said carrier.
Claim 7
Dependent Claim
28 words
The machine according to claim 5 wherein said holding means includes a creaser blade positioned in the slot in the forming block and biased to engage said carrier.
Claim 8
Dependent Claim
36 words
The machine according to claim 6 wherein said carrier includes a groove along one edge and said blade is positioned to move into engagement with said groove to form an indent in the strip of material.
Claim 9
Dependent Claim
19 words
The machine according to claim 6 wherein said guiding means is mounted for horizontal movement with said forming block.
Claim 10
Dependent Claim
23 words
The machine according to claim 1 wherein said forming means includes means for forming an indent in the end of the cell material.
Claim 11
Dependent Claim
174 words
A cell inserting apparatus for cutting, forming and inserting cells into the slots of a stator, said assembly including an insertion bar having a cell carrier, a cell former having a slot to receive said carrier, a cell creaser blade positioned in said slot in said former, means for moving said blade to a position to hold said strip of cell material against said insertion bar prior to cutting, said blade simultaneously creasing said cell material during the initial movement of said cell former, means for cutting said strip of material into predetermined lengths, means for moving said former to a position to wrap said cut strip around said carrier, a plow positioned in the path of motion of said cell carrier, said plow having a tapered slot shaped to confrom the cell to the shape of the slot in said stator, and means for moving said insertion bar toward the slot of the stator whereby the cell formed on the cell carrier is carried through the plow into the slot of the stator.
Claim 12
Dependent Claim
174 words
A cell inserting apparatus for cutting, forming and inserting cells into the slots of a stator, said assembly including an insertion bar having a cell carrier, a cell former having a slot to receive said carrier, a cell creaser blade positioned in said slot in said former, means for moving said blade to a position to hold said strip of cell material against said insertion bar prior to cutting, said blade simultaneously creasing said cell material during the initial movement of said cell former, means for cutting said strip of material into predetermined lengths, means for moving said former to a position to wrap said cut strip around said carrier, a plow positioned in the path of motion of said cell carrier, said plow having a tapered slot shaped to confrom the cell to the shape of the slot in said stator, and means for moving said insertion bar toward the slot of the stator whereby the cell formed on the cell carrier is carried through the plow into the slot of the stator.
