Abstract
A machine for creasing and slitting a travelling web, such as a cardboard web, characterized by an assembly which includes a carriage having a tool storage device with at least one spare tool and a lever arm mounting a tool for rotation. The lever arm is movable from a position with the tool engaging the web passing through the machine to a withdrawn position which enables changing the tool with one of the spare tools. Each of the assemblies is adjustably positioned in a transverse direction relative to the direction of movement of the web. The device includes a second group of assemblies which contains counter-tools for the tools of the first group.
Claims18
A machine for creasing and slitting a travelling web, said machine comprising creasing and slitting means including a tool a frame containing first means designed for setting an operating position of the tool in a direction extending perpendicular to a travelling direction of the web, a storage device being positioned in said frame containing at least one spare tool, second means for transferring the tool between the operating position engaging the web and a spare position, and means for rotating the tool when in the operating position, the first means including a carriage, means mounting the carriage in the frame for shifting the carriage to various positions in a direction perpendicular to the travelling direction of the web, said storage device comprising a turret mounted on said carriage and having a plurality of tool seats, and a lever mounted on said carriage for supporting the tool and being movable on the carriage to transfer the tool between a first position with the tool in the operating position engaging the web and a second position at a seat said turret spaced from the web to enable transferring tools between the operating position and said spare position of said storage device.
In a machine for creasing and slitting a travelling web, said machine comprising creasing and slitting including a tool frame containing means designed for setting the operating position of a tool in a direction extending transverse to the travelling direction of the web, at least one storage device for supporting at least one spare tool, means for transferring the tool from an operating position engaging the web to a spare position and means for rotatably driving the tool in the operating position, the improvements comprising the machine including at least one carriage, means for mounting the carriage in said frame for movement in the transverse direction, a lever being mounted on the carriage for moving the storage device between a first position and a second position, said storage device being a turret having several seats for receiving tools, said turret being mounted for rotation on said lever to present one of said several seats to a position for being an operating seat so that when said lever is pivoted to the first position, the tool in the operating seat engages the web and when said lever is pivoted to the second position, the tool in the operating seat is spaced from the web and means for rotating the turret to present different seats at the position of said operating seat when said lever is in the second position.
