An apparatus for holding a tool in machinery and having a tool holder contable to the machine, with a cylindrical receptacle into which the cylindrical shaft of a tool is inserted rotatably and removably. The tool holder is detachably and rigidly connectable by an improved self-locking dovetail connection to a base plate which is rigidly connected to the machine. The base plate or the tool holder is provided in the area of the dovetail connection with arrest serrations running transverse to the insertion direction and on the opposing tool holder or base plate, oriented adjacent to the arrest serrations, there is installed a spring-loaded holding bolt or a stop spring which engages either with the arrest serrations of the base plate or of the tool holder, respectively, and enhances the connection between the base plate and the tool holder.

Apparatus for retaining a tool in machinery

An apparatus for producing blanks from a web including a pair of relatively movable upper and lower blades for severing therebetween blanks from a web along a predetermined cut line established by cooperative cutting edges of the blades, an end feed path of travel for the web and a discharge path of travel for the blanks, a mechanism for rotating the blades to selectively vary the cutting angle and thereby vary the sizes, shapes and/or cut line orientation of the blanks severed from the web, a transfer mechanism for transferring each severed blank from a position adjacent the blades and the end feed path of travel to a second position at the blank discharge path of travel, the transfer mechanism including a receiving element pivoted to an arm which in turn is pivoted for movement in a generally horizontal plane, the receiving element be accommodated in a recess adjacent the blades and receiving therein each severed blank for transfer to the discharge path of travel.
