6. The slicing machine according to claim 1 , characterized in that the locking disc ( 17 c ) can be displaced synchronously with the carriage ( 14 ) on the sliding rail ( 15 c ), and a locking rib ( 19 ) is provided on the machine housing ( 11 ), which, in a certain angular position of the locking disc ( 17 c ) about the sliding rail ( 15 c ), interacts with a profile of the machine housing ( 11 ) such that the carriage ( 14 ) can be swung out only in a certain axial position of the carriage ( 14 ) relative to the sliding rail ( 15 c ), in particular in an end position.

7. The slicing machine according to claim 6 , characterized in that the profile is integrally formed, cast, bonded, or screwed on the machine housing ( 11 ).

8. The slicing machine according to claim 1 , characterized in that a pivotably supported locking strip ( 29 ) is disposed such that it transfers the movement of the locking disc ( 27 c ) to the second push rod ( 27 d ).

9. The slicing machine according to claim 1 , characterized in that the sliding rail ( 15 c ; 25 c ) is mounted or attached at both of the opposite end faces thereof in an end wall of the machine housing ( 11 ; 21 ), and in that the two end walls cover the guide space (F; F′) enclosed by the separating wall ( 16 ; 26 ) on both end faces.

10. The slicing machine according to claim 1 , characterized in that the carriage base ( 14 a ; 24 a ) is supported such that it is movable relative to the machine housing ( 11 ; 21 ) via at least two support elements ( 15 a , 15 b ; 25 a , 25 b ), and in that the at least two support elements ( 15 a , 15 b ; 25 a , 25 b ) are movably accommodated within the guide space (F; F′) and bear against the separating wall ( 16 ; 26 ), wherein, in an operating state of the slicing machine ( 10 ; 20 ), the first support element ( 15 a ; 25 a ) bears from below against the surface of a first separating wall section ( 16 a ; 26 a ) of the separating wall ( 16 ; 26 ) that faces away from the carriage ( 14 ; 24 ), the separating wall extending underneath the support plate ( 13 ; 23 ) parallel to the plane (A; A′) of the support plate ( 13 ; 23 ), and in that the separating wall ( 16 ; 26 ) comprises a second separating wall section ( 16 b ; 26 b ) that extends downwardly in a straight or slanted manner at an angle with respect to the first separating wall section ( 16 a ; 26 a ), wherein the second support element ( 15 b ; 25 b ) bears laterally against the second separating wall section ( 16 b ; 26 b ).
