Abstract
A method for joining together two webs includes: overlapping a head portion of the second web on a tail portion of the first web, jointly cutting the head portion of the second web and the tail portion of the first web along a cutting line, so as to form on the first web and on the second web respective front edges offset from each other, and applying a first adhesive splicing tape between a head end of the second web and a tail end of the first web and at the same time aligning frontally with each other the front edges of the first and the second webs.
Claims18
A method for producing cellulose fluff, comprising:
- providing a defibrator mill having two inlets,
- simultaneously feeding a first web and a third web to respective inlets of the defibrator mill, and
- joining tail portions of the first and third webs to head portions of second and fourth webs,
- wherein said joining step comprises:
- overlapping a head portion of the second or fourth web with a tail portion of the first or third web,
- holding a head portion of the second or fourth web with a tail portion of the first or third web in a stationary position,
- jointly cutting the head portion of the second or fourth web and the tail portion of the first or third web along a cutting line, so as to form on the first or third web and on the second or fourth web respective front edges offset from each other, and
- applying a first adhesive splicing tape between a head end of the second or fourth web and a tail end of the first or third web and at a same time aligning frontally with each other the front edges of the first or third web and the second or fourth web.
A machine for producing cellulose fluff, comprising:
- a defibrator mill having two inlets,
- a first reel-holder assembly configured to carry a first reel and a second reel containing, respectively, a first and a second web,
- a second reel-holder assembly configured to carry a third reel and a fourth reel containing, respectively, a third and a fourth web, and
- a first and a second splicing apparatus, wherein each of said first and second splicing apparatuses comprises:
- a stop unit configured to hold in stationary conditions in an overlapping position a tail portion of the first or third web and a head portion of the second or fourth web,
- a cutting device configured for jointly cutting the head portion of the second or fourth web and the tail portion of the first or third web along a cutting line, so as to form on the first or third web and on the second or fourth web respective front edges offset from each other, and
- a first applicator device configured for applying a first adhesive splicing tape between a head end of the second or fourth web and a tail end of the first or third web and at the a same time aligning frontally with each other the front edges of the first or third web and the second or fourth web.
