Process and apparatus for cutting a running material web

An apparatus for cutting a running material web in which the material web is wound onto several winding cores in succession, the apparatus comprising:

• at least one cutting device structured and arranged to completely cut the material web;
• a movable transport device;
• and
• said at least one cutting device being movably mounted on said movable transport device via at least one of a continuous element and a piston/cylinder unit for movement relative to the material web in a plane substantially parallel to the material web.

An apparatus for cutting a running material web in which the material web is wound onto several winding cores in succession, the apparatus comprising:

• at least one cutting device adapted to completely cut the material web;
• said at least one cutting device being mounted for movement relative to the material web in a plane substantially parallel to the material web;
• a transport device having at least one cylinder/piston unit;
• and
• said piston being coupled, on one end, to said at least one cutting device.

An apparatus for cutting a running material web in which the material web is wound onto several winding cores in succession, the apparatus comprising:

• at least one cutting device adapted to completely cut the material web;
• said at least one cutting device being mounted for movement relative to the material web in a plane substantially parallel to the material web;
• an old winding core on which a wound roll is being wound;
• a new winding core on which a next wound roll will be wound;
• and
• a winding roll,
• wherein said at least one cutting device is located between said new winding core and said wound roll.

An apparatus for cutting a running material web in which the material web is wound onto several winding cores in succession, the apparatus comprising:

• at least one cutting device adapted to completely cut the material web;
• said at least one cutting device being mounted for movement relative to the material web in a plane substantially parallel to the material web;
• an old winding core on which a wound roll is being wound;
• a new winding core on which a next wound roll will be wound;
• and
• at least one deflection roll located upstream from said new winding core,
• wherein said cutting device is arranged upstream from said at least one deflection roll.

A process for cutting a running material web in which the material web is wound onto several winding cores in succession, such that winding of the material web onto a new winding core begins after a predetermined diameter has been attained in a wound roll formed on an old winding core, the process comprising:

• moving the new winding core between a winding roll and the wound roll, wherein the material web is fed onto the wound roll from the winding roll;
• forming a nip between the new winding core and the winding roll;
• positioning at least one cutting device one of in a vicinity of the winding roll;
• and
• moving the at least one cutting device, which is movably mounted on a transport device via at least one of a continuous element and a piston/cylinder unit, relative to the material web in a plane substantially parallel to the material web, whereby the running material web is completely cut.
