The tools are conducted between guide rails in a lengthwise shiftable manner. The lengthwise feed of the tools in the tool magazine takes place by means of a feed comb whose comb teeth are moved transversely into engagement between the individual tools. The feed comb carries out a driven feed movement in a lengthwise direction of the magazine. The tools are moved from the tool magazine by a tool gripping device and conducted to a tool fixture of the tool machine. Conversely, the expended tools are moved into the tool magazine by a tool gripping device. ## Claims ### Claim 1 In a tool machine of the type comprising at least one tool magazine which removably

Apparatus according to claim 3, wherein said feeding means comprises a pair of drive journals which connect with said feed comb and stdp comb, respectively, and project from said magazine, and a drive mechanism on said fixture to which said journals are operably connected. ### Claim 9 (depends on 8) Apparatus according to claim 8, wherein said drive mechanism comprises a coulisse part which is displaceable in the lengthwise direction and which includes a transversely wide groove in which the drive journal of the stop comb projects, a slide valve mounted in said coulisse part and including a deflecting strip projecting into said groove, said drive journal of said stop comb being displaceable transversely in said groove by said deflecting strip to move said teeth of said stop comb. ### Claim 10 (depends on 9) Apparatus according to claim 9 including means for shifting said deflecting strip transversely in response to said coulisse part reaching either end of its stroke. ### Claim 11 (depends on 1) Apparatus according to claim 1, wherein there are a plurality of parallel guide tracks each including opposite guide rails which engage guide grooves in said tools. ### Claim 12 (depends on 11) Apparatus according to claim 11, wherein said guide grooves and guide rails have V-shaped cross-sections. ### Claim 13 (depends on 11) Apparatus according to claim 11, wherein at least one rail of each guide track can be shifted transversely against a return spring bias. ### Claim 14 (depends on 11) Apparatus according to claim 11, wherein said gripping device includes gripper rails engageable with said guide grooves of said tools. ### Claim 15 (depends on 14) Apparatus according to claim 14, wherein both guide grooves of each tool include a depression in which a projection of said gripper rail may engage to releasably hold said tool. ### Claim 16 (depends on 11) Apparatus according to claim 11, wherein both said opposite guide rails are provided on said magazine. ### Claim 17 (depends on 16) Apparatus according to claim 16, wherein both guide rails are interconnected by a gantry overlying said tools. ### Claim 18 (depends on 1) Apparatus according to claim 1, wherein there are a plurality of said magazine mounted for replacement on said fixture. ### Claim 19 (depends on 1) Apparatus according to claim 1, wherein said feed comb is mounted for rotation about a
