This disclosure relates to an indexing feed mechanism for a cutting machine comprising an indexing vise for gripping a workpiece and moving it forward into a cutting position. The mechanism includes a lead screw interengaged with complementary means formed on a stopper means adapted to limit the rearward extent of the stroke of the indexing vise. Rotation of said screw will, therefore, cause translation of said stopper means thereby varying the rearward limit of travel of the indexing vise during its stroke. The lead screw extends from a rotatable shaft and means located at the operating station of the cutting machine are provided for rotating the shaft. The shaft is operably connected to a digital indicator which indicates in digital numerals the predetermined stroke of the indexing vise as a function of the angular position of the shaft.
A material indexing feed mechanism for a cutting machine such as a horizontal bandsaw machine or the like comprising an indexing vise for gripping a workpiece and moving it forward toward an operating station of said machine into a cutting position, means defining a path of travel for said indexing vise, means for moving said indexing vise back and forth along said path, stopper means for limiting the rearward extent of said indexing vise along said path in a direction away from said cutting position, means carried by said stopper means operatively connected with said moving means for stopping the operation of said moving means upon engagement therewith by means carred by said vise, a lead screw interengaged with complimentary means on said stopper means and extending parallel to said path for adjusting the position of said stopper means, said lead screw being connected to a rotatable shaft which extends to said operating station of said machine, and means located at said operating station for rotating said shaft, whereby rotation of said lead screw through said shaft will cause translation of said stopper means along said path thereby varying the rearward limit of travel of said indexing vise.
Apparatus for cutting material in incremental lengths comprising a feed table, cutting means mounted at a cutting position and movable in a plane extending generally transverse to said table, a first vise fixed with respect to said table for holding the material in position to be cut, a second vise movable with respect to said table for indexing the material in incremental lengths along a path to said cutting position, means for moving said movable vise back and forth along said path, stop means for limiting the rearward extent of said movable vise along said path in a direction extending away from said cutting station, means for adjusting the position of said stop means along said path thereby varying the length of the indexing increment, said adjusting means including operating means disposed on the opposite side of said cutting plane from said first and second vises.
