Abstract
Process and winding machine for winding a continuous material web on a reel spool forming a wound reel. The process includes, upon attaining a desired roll diameter in an old wound reel, closing a new winding nip between a reeling drum and a new reel spool brought into a standby position. In this regard, the reeling drum and the old wound reel are jointly displaced while maintaining the old winding nip formed between the reeling drum and the old wound reel. After the closing of the new winding nip between the reeling drum and the new reel spool, the linear load in the new winding nip is adjusted, controlled or regulated by a corresponding displacement and tightening of the reeling drum.
Claims57
A process for winding a continuous material web on a reel spool forming a wound reel, comprising:
- forming a winding nip between a displaceable reeling drum and an old wound reel, which is displaceably mounted in a secondary transport device;
- adjusting, controlling or regulating a linear load (LKSekNip) in the winding nip by a corresponding displacement and tightening of the reeling drum;
- guiding the material web over the displaceable reeling drum that, with the old wound reel displaceable by a secondary transport device, forms a winding nip;
- bringing a new reel spool into a stand-by position;
- jointly moving the reeling drum and the old wound reel while maintaining the winding nip formed between the reeling drum and the old wound reel when the old wound reel attains a preset diameter whereby a new winding nip is formed between the new reel spool in the stand-by position and the reeling drum;
- adjusting, controlling, or regulating a linear load (LKPrimNip) in the new winding nip by a corresponding displacement and tightening of the reeling drum;
- separating the material web by at least one separator device to form a new web leader;
- winding the new web leader onto the new reel spool;
- removing the old wound reel from the reeling drum, thereby opening the winding nip;
- and
- moving the new reel spool in a primary transport device while maintaining the new winding nip until the position of the new winding nip corresponds to the position where the winding nip was located.
A winding machine for the continuous winding of a material web on a reel spool forming a wound reel, comprising:
- a displaceable reeling drum having a circumferential area structured to receive the material web;
- a secondary transport device structured and arranged to displace an old wound reel;
- said reeling drum and the old wound reel being arranged to form a winding nip and a linear load (LKSekNip) in said winding nip is controlled or regulated by a corresponding displacement and tightening of, said reeling drum;
- a device locating a new reel spool into a stand-by position, wherein, when a preset wound reel diameter is attained, said reeling drum and the old wound reel are structured and arranged to jointly move toward said stand-by position, while maintaining the winding nip, to form a new winding nip between the new reel spool and said reeling drum;
- at least one web separating device is structured and arranged to separate the material web and to form a new web leader;
- said secondary transport device is movable to open the winding nip and to move said old wound reel away from said reeling drum;
- a primary transport device is structured and arranged to move the new reel spool from the stand-by position to a position at which the winding nip was located while maintaining the new winding nip;
- wherein a linear load (LKPrimNip) in the new winding nip is adjustable, controllable or regulatable by a corresponding displacement and tightening of the reeling drum.
