Method and apparatus for winding

An apparatus for winding a web of material into a roll having a generally constant tension and compression, comprising:

• winding means for accumulating a web of material;
• distributing means for distributing said web of material onto said winding means;
• driving means for rotating said winding means;
• and,
• regulating means for maintaining a speed ratio between said winding means and said distributing means;
• wherein said distributing means is spaced apart from, but in close proximity to, the web of material accumulated on said winding means, and wherein said distributing means is in direct contact with said web of material being distributed onto said winding means and wherein said regulating means operates said driving means and is responsive to the speed changes of said distributing means.

An apparatus for winding, comprising:

• winding means for rotatingly accumulating a web of material;
• distributing means, in lose proximity to said winding means, for presenting the web of material onto said winding means;
• driving means for rotating said winding means;
• and
• regulating means for maintaining a constant surface speed ratio between an outermost surface of said material accumulated on said winding means and an outer surface of said distributing means;
• wherein said outer surface of said distributing means is spaced apart from, but in close proximity to, said outermost surface of said material accumulated on said winding means, and wherein said outer surface of said distributing means is in direct contact with said web of material being distributed to said winding means;
• and
• wherein said regulating means operates said driving means and is responsive to the speed changes of said outer surface of said distributing means.

An apparatus for winding, comprising:

• a winding roll having a cylindrical outer surface, wherein said winding roll rotatingly accumulates a web of material around said outer surface;
• a lay-on roll having an outer surface, wherein said lay-on roll feeds a web of material onto said outer surface of said winding roll at a speed not less than the surface speed of said material accumulated on said outer surface;
• said lay-on roll being in close proximity to, but not touching, said material accumulated on said outer surface of said winding roll;
• at least one dancer roll for exerting adjustable pressure against said web of material before said web passes over said lay-on roll;
• a motor for driving said winding roll;
• regulating means for regulating said motor so as to maintain an essentially constant speed ratio between said outer surface of said lay-on roll and said outermost surface of said material accumulated on said winding roll;
• and
• wherein the pressure exerted against said web of material by said dancer roll varies to control the tension in said web of material, and wherein said lay-on roll is in direct contact with said material being fed to said winding roll.

An apparatus for winding, comprising:

• winding means for accumulating a web of material;
• distributing means for distributing said web of material onto said winding means;
• driving means for rotating said winding means;
• and
• regulating means for maintaining a speed ratio between said winding means and said distributing means;
• wherein said distributing means is spaced apart from, but in close proximity to, the web of material accumulated on said winding means, and wherein said distributing means is in direct contact with said web of material being distributed onto said winding means and wherein said regulating means operates said driving means and is responsive to changes in the surface speed of said distributing means.

An apparatus for winding, comprising:

• a winding roll for accumulating a web of material;
• a lay-on roll for distributing said web of material to said winding roll;
• a driver for rotating said winding roll;
• a regulator for maintaining an adjustable speed ratio between said winding roll and said lay-on roll;
• and
• means for sensing the tension of said web of material;
• and
• wherein said lay-on roll does not contact said material accumulated on said winding roll and wherein the tension of said web of material being wound is controlled by said tension sensing means.

An apparatus for winding, comprising:

• a winding roll for accumulating a web of material;
• a lay-on roll for distributing said web of material to said winding roll;
• a driver for rotating said winding roll;
• regulator means for regulating the speed ratio between said winding roll and said lay-on roll, said regulator means including sensing means responsive to tension variations in said web;
• wherein said lay-on roll does not contact said material accumulated on said winding roll.
