摘要： A clamping device for thin flexible printing plates has a tensioning rail at the trailing wall of a wide longitudinal groove in the plate cylinder. The tensioning unit is mounted for axial and peripheral adjustment on a support of "L" cross-section having a first leg seated with respect to the bottom of the groove and a second leg presenting an upstanding reference surface interposed between the tensioning rail and the trailing wall of the groove. A set of tensioning springs recessed in the tensioning rail bear against the reference surface and apply peripheral tension to the plate. A spring detent latches the tensioning rail temporarily against the reference surface, overcoming the tensioning springs while the trailing edge of the plate is being gripped. The spring detent is mounted upon and movable with the support. Screws having a plurality of selectable holes anchor the support in a series of peripheral positions for accommodation of plates of different length. A plurality of jack screws threaded into the tensioning rail have tips which bear against the reference surface on the support for removing slack from the plate and for tensioning of the plate about the surface of the cylinder.

摘要： A device for establishing the initial distance between the surface of a grinding tool and the surface of a workpiece to be ground. A combination of an active and a passive sensing element rigidly connected at a known distance is positioned between the workpiece and the grinding tool. The workpiece is brought into contact with the passive sensing element and both the workpiece and sensing elements are moved toward the grinding tool while maintaining contact. The active sensing element senses the grinding tool when the distance between the tool and the workpiece is equal to the distance between the active and passive sensing elements. When this occurs, the active sensing element provides a signal and therefore the distance at which the grinding wheel will meet the workpiece can be calculated. A fixed abutment is also provided so that absolute measurements of the dimensions of the workpiece or grinding tool can be obtained.

摘要： A method and a device for the automatic removal of burrs or fins from workpieces such as castings by a grinding process. A feed for moving the workpiece perpendicular to the grinding wheel radius is provided for grinding along the length of the burr. A second constant velocity feed of reversible and alternating direction is provided for moving the grinding wheel radially into the workpiece. The load or circumferential torque on the grinding wheel is monitored to detect the abrupt increase in torque occurring when the grinding wheel has cut through the burr and encounters the body of the workpiece, whereupon the direction of the radial feed is reversed so that the grinding process follows the contour of the workpiece.
