Claim 6

An apparatus according to claim 3, in which, at the level of said lower shelf bottoms, both of said magazine rows are interrupted to form common passage means.

Claim 7

An apparatus according to claim 3, in which said means for conveying tools between said lower and upper shelf bottoms includes at least one mechanism that comprises two further shelf bottoms that are interconnected in the manner of a weight compensator and are moved together via a drive shaft.

Claim 8

An apparatus according to claim 5, in which, in a starting position, said further shelf bottoms are disposed at the level of said upper and lower shelf bottoms.

Claim 9

An apparatus according to claim 5, in which said conveying means also includes a mechanism with additional shelf bottoms that is adapted to convey tools from a loading position to the level of said upper shelf bottoms of said magazine rows.

Claim 10

An apparatus according to claim 3, in which said means for conveying tools between said lower and upper shelf bottoms includes at least one mechanism that comprises a single further shelf bottom that can be moved up and down, with chain means being provided to effect said movement, with said chain means having an end that is remote from said further shelf bottom and either carries a counterweight or is looped about a drive shaft.

Claim 11

An apparatus according to claim 3, in which said upper transport rail of said upper transport mechanism is linear and continuous; in which said lower shelf bottoms of one of said magazine rows are interrupted by gaps; and in which said lower transport rail of said lower transport mechanism is interrupted at said gaps of said lower shelf bottoms, with said transport mechanisms being guided and movable on said transport rails.

Claim 12

An apparatus according to claim 9, in which said interrupted lower transport rail is provided with extensions that branch off at right angles thereto and extend to said processing machines parallel to a longitudinal axis thereof.

Claim 13

An apparatus according to claim 9, in which said lower transport rail, in the region of said gaps of said lower shelf bottoms, has curved rail sections that angle-off from said lower transport rail and respectively merge into a further guide rail for a lower transport mechanism, with said further guide rail extending parallel to a longitudinal axis of said processing machines.

Claim 14

An apparatus according to claim 3, in which each of said transport rails has several transport mechanisms associated therewith.

Claim 15

An apparatus according to claim 3, in which each of said transport mechanisms is provided with at least one pivot arm having a free end for carrying said gripper means for said tools.

Claim 16

An apparatus according to claim 13, in which said shelf bottoms include recesses with rims for engaging tools; in which each tool has a shank with a head, and an annular bead; and in which each gripper means of said transport mechanisms includes a lifting mechanism, for engaging said head of said tool shank, and an arm that is disposed in the vicinity of said annular bead between the latter and said head of said tool shank, with said arm having an underside, remote from said head of said tool shank, against which said annular bead of said tool is pressed when said lifting mechanism lifts said annular bead from said rim of said recess of said shelf bottom.
