Tool head positioning mechanism for a converting machine, and method for positioning a plurality of tool heads in a converting machine

A method for positioning a plurality of tool heads in a converting machine for converting sheet material into box templates, comprising:

• providing a plurality of tool heads located at a first set of individual positions within a converting area,
• simultaneously moving the plurality of tool heads within the converting area in a first movement by means of a joint transport mechanism that is arranged to be coupled individually to each tool head,
• moving at least one of the plurality of tool heads relative to the transport mechanism and the other tool heads in a second movement,
• wherein the plurality of tool heads are moved to a second set of individual positions by the first and second movement, and wherein the second movement takes place during the first movement.

A tool head positioning device for a converting machine for converting sheet material into box templates, comprising:

• a plurality of tool heads arranged in a converting area and able to act on sheet material being transported through said converting area,
• a joint transport mechanism having a conveyor arrangement that is arranged to be coupled to each of the tool heads and to perform a first movement of the plurality of tool heads within the converting area by the conveyor arrangement moving together with the tool heads, and
• a plurality of individual transport mechanisms, each arranged at a tool head and able to perform a second movement of that tool head relative to the conveyor arrangement, wherein the individual transport mechanisms each comprise a motor connected to the tool head, wherein said motor acts on the conveyor arrangement to move the tool head along the conveyor arrangement,
• wherein the joint transport mechanism and the plurality of individual transport mechanisms are arranged to move the plurality of tool heads from a first set of individual positions to a second set of individual positions.
