Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
106 words
Method of supplying a metal plate to, positioning the same in and removing the same from a processing machine which comprises the steps of: advancing said metal plate on a feeding table electromagnetic induction force toward said processing machine, stopping said metal plate with a retractable stopper member by projecting said stopper member above the surface of the feeding table, laterally moving said metal plate by electromagnetic induction force up to a predetermined position wherein said metal plate is stopped by a side guide member, and removing said metal plate from said predetermined position by retracting said stopper member below the surface of the feeding table.
Claim 2
Dependent Claim
106 words
Method of supplying a metal plate to, positioning the same in and removing the same from a processing machine which comprises the steps of: advancing said metal plate on a feeding table electromagnetic induction force toward said processing machine, stopping said metal plate with a retractable stopper member by projecting said stopper member above the surface of the feeding table, laterally moving said metal plate by electromagnetic induction force up to a predetermined position wherein said metal plate is stopped by a side guide member, and removing said metal plate from said predetermined position by retracting said stopper member below the surface of the feeding table.
Claim 3
Dependent Claim
44 words
Method of supplying a metal plate to, positioning the same in and removing the same from a processing machine as defined in claim 1 wherein said predetermined position is the position in which the metal plate is to be processed in the processing machine.
Claim 4
Dependent Claim
115 words
Method of supplying a metal plate to, positioning the same in and removing the same from a processing machine which comprises the steps of: feeding said metal plate on a feeding table electromagnetic induction force toward said processing machine, stopping said metal plate with a stopper member, laterally moving said metal plate by electromagnetic induction force up to a predetermined position where said metal plate is stopped by a side guide member and where said plate is to be processed by said processing machine , and removing said metal plate from said predetermined position by an electromagnetic induction force energized in the opposite direction to that for feeding said metal plate toward said processing machine.
Claim 5
Dependent Claim
115 words
Method of supplying a metal plate to, positioning the same in and removing the same from a processing machine which comprises the steps of: feeding said metal plate on a feeding table electromagnetic induction force toward said processing machine, stopping said metal plate with a stopper member, laterally moving said metal plate by electromagnetic induction force up to a predetermined position where said metal plate is stopped by a side guide member and where said plate is to be processed by said processing machine , and removing said metal plate from said predetermined position by an electromagnetic induction force energized in the opposite direction to that for feeding said metal plate toward said processing machine.
Claim 6
Dependent Claim
80 words
Method of supplying a metal plate to, positioning the same in and removing the same from a processing machine as defined in claim 3 wherein side guide member is rotatable about an axis transverse to the surface of the feeding table on which said metal plate is fed, and said side guide member is positioned at a predetermined angle before said metal plate is moved laterally, whereby said metal plate is processed at the predetermined angle by the processing machine.
Claim 7
Independent Claim
150 words
An apparatus for supplying a metal plate to, positioning the same in and removing the same from a processing machine which comprises a feeding table having an electromagnetic induction type feeding unit under the surface thereof, said feeding table being disposed at the upstream and downstream ends of a processing machine, said feeding table including an electromagnetic induction type positioning unit under the surface thereof near said processing machine for moving said metal plate laterally on said table, a retractable stopper member provided at the downstream end of said processing machine for stopping the advancement of said metal plate by said feeding unit at a position on said table position near said processing machine, and side guide means disposed at the upstream and downstream ends of said processing machine for stopping the lateral movement of said metal plate by said positioning unit at a predetermined position on said feeding table.
Claim 8
Independent Claim
