Abstract
Abstract An apparatus for trimming the respective four sides of a flat elastomeric stock. The apparatus includes a pair of trim stations interconnected by a transfer conveyor wherein the respective trimming machines trim at least a pair of sides. Each of the trimming machines are adjustable automatically to compensate for variations in width as well as height of the panels of material.

Claim 3
Dependent Claim
92 words
An apparatus for processing panels as set forth in claim 1 wherein each of said guide means includes a longitudinally extending guide plate member with recesses therein, each of said recesses having a roller therein, the axes of said rollers being vertical in the operative position of said guide members, a plane tangent to the respective rollers being respectively in alignment with said cutters, and each of said guide members having a resiliently mounted pressure plate biased downward toward said conveyor means and being normal to said supporting longitudinal guide plate member.
Claim 4
Dependent Claim
45 words
An apparatus for processing panels as set forth in claim 1 wherein pneumatic cylinder means are connected to said biasing means, said pneumatic cylinder means operative upon energization to act against said biasing means and move said one guide means away from said center line.
Claim 5
Dependent Claim
225 words
Apparatus for processing panels of sheet material comprising support means, conveyor means for moving panels thereon, said conveyor means having a longitudinal pass line, a pair of laterally spaced cutters at one end of said conveyor means for trimming opposed side edges of a panel passing therebetween, a pair of guide means mounted on said support means on opposite sides of the conveyor means for centering said panel on said conveyor means while passing said cutters, each of said guide means having a resiliently mounted pressure plate movable therewith to adjust for thickness of panels upon movement of said resiliently mounted plates into a horizontally disposed position, one of said guide means movable laterally towards and away from said longitudinal center line, means interconnecting said one guide means and one of said cutters for simultaneous movement, the other said guide means and cutter having a fixed mounting with respect to the longitudinal center line, biasing means connected to said one guide means and said one cutter for biasing said one guide means and said one cutter toward said longitudinal center line to adjust the distance between said cutters in response to the width of a panel received by said conveyor means and said guide means, and power operated means connected to the guide means for pivoting said guide means into operative and inoperative positions, respectively.
Claim 6
Dependent Claim
225 words
Apparatus for processing panels of sheet material comprising support means, conveyor means for moving panels thereon, said conveyor means having a longitudinal pass line, a pair of laterally spaced cutters at one end of said conveyor means for trimming opposed side edges of a panel passing therebetween, a pair of guide means mounted on said support means on opposite sides of the conveyor means for centering said panel on said conveyor means while passing said cutters, each of said guide means having a resiliently mounted pressure plate movable therewith to adjust for thickness of panels upon movement of said resiliently mounted plates into a horizontally disposed position, one of said guide means movable laterally towards and away from said longitudinal center line, means interconnecting said one guide means and one of said cutters for simultaneous movement, the other said guide means and cutter having a fixed mounting with respect to the longitudinal center line, biasing means connected to said one guide means and said one cutter for biasing said one guide means and said one cutter toward said longitudinal center line to adjust the distance between said cutters in response to the width of a panel received by said conveyor means and said guide means, and power operated means connected to the guide means for pivoting said guide means into operative and inoperative positions, respectively.
