The invention relates to an apparatus for longitudinally dividing sheet material, said apparatus comprising a cutter bar (1) that is oriented crosswise to the movement direction of the sheet material and is provided with a guide (7) on which knife holders (2) are positioned such that they can be displaced. The knife holders are respectively provided with a immobilizing brake (18), comprising at least one movable brake block (18.1, 18.2), which acts via at least one force means (21) upon a parallel braking surface (20.1, 20.2), arranged so as to extend in longitudinal direction on the cutter bar. The force means is designed to immobilize the knife holder to be positioned ob the cutter bar (1) during the operation, wherein the force exerted by the brake block is oriented in the guide plane defined by the guide. The device is further provided with a positioning device (10) that is guided along the cutter bar (1) for positioning the individual knife holders (2). The positioning device comprises a coupling means (13) that can be activated and can be made to engage in the respective knife holder to be positioned and, upon engagement, releases the brake block (18.1, 18.2) of the immobilizing brake (18) from the braking surface (20.1, 20.2).
An apparatus for longitudinally dividing sheet material, comprising a cutter bar (1) that is aligned transverse to the movement direction of the sheet material and is provided with a guide (7) on which knife holders (2) are positioned so as to be displaceable, said knife holders being respectively provided with an immobilizing brake (18) with at least one movable brake block (18.1, 18.2) that acts via at least one force means (21) upon a braking surface (20.1, 20.2), extending parallel to its longitudinal direction and immobilizes the knife holder to be positioned during the operation on the cutter bar (1), wherein the force effect of the brake block is oriented in the guide plane defined by the guide, said device further having a positioning device (10) guided on the cutter bar (1) for positioning the individual knife holders (2), which device comprises a coupling means (13) that can be actuated and can be made to engage with the respective knife holder to be positioned and, once it is engaged, releases the brake block (18.1, 18.2) of the immobilizing brake (18) from the braking surface (20.1, 20.2).
An apparatus according to one of the claims 1 to 3, characterized in that the braking surface (20.1, 20.2) is a brake beam (20) that is arranged on the cutter bar (1).
