Abstract
Apparatus for winding web material (14) comprises a reciprocating carriage assembly (22) which delivers the leading end of the web to a winding spindle (30) and then moves away from the spindle as winding proceeds. A builder roll (138) mounted on the carriage assembly applies pressure during winding. A tape tab (178) is automatically applied to the trailing end of the web and pressed onto the completed roll (140) by the builder roll, while a stepping motor (176) for the builder roll resists the winding motor to maintain tension in the final convolution of the web. A corresponding method is taught.
Claims17
Apparatus for winding web material onto a spool, said apparatus comprising:
- a source of web material to be wound;
- a first frame;
- means mounted on said first frame for rotating said spool about an axis to wind said web material onto said spool;
- a second frame;
- means mounted on said first frame for permitting said second frame to move toward or away from said axis;
- roll means mounted on said second frame for engaging an outermost convolution of said web material during winding onto said spool;
- means mounted on said first frame for moving said second frame on said means for permitting toward said axis to facilitate attachment of said leading end to said spool and away from said axis to allow continued winding of said web material onto said spool;
- means mounted on said second frame for pressing said roll means against said outermost convolution as a trailing end of said web material nears said spool;
- means for stopping said spool while maintaining torque thereon;
- means mounted on said second frame for applying a tab of adhesive tape to a trailing end of said web material before said trailing end passes said roll means, said tab of adhesive tape having an adhesive portion extended beyond said trailing end, whereby said adhesive portion of said tab of adhesive tape is rolled by said roll means onto an underlying convolution of said web material to secure said trailing end;
- and
- motor means for controllably rotating said roll means in contact with said outermost convolution and said tab of adhesive tape as said spool is rotated, in order to maintain tension in said web material as said tab of adhesive tape is applied to said underlying convolution.
A method for winding web material onto a spool, said method comprising the steps of:
- rotating said spool about an axis to wind said web material onto said spool;
- engaging an outermost convolution of said web material with a roll during winding onto said spool;
- pressing said roll against said outermost convolution as a trailing end of said web material nears said spool;
- stopping said spool while maintaining torque thereon;
- applying torque to said roll to maintain tension on said outermost convolution;
- applying a tab of adhesive tape to said trailing end before said trailing end passes said roll, said tab of adhesive tape having an adhesive portion extending beyond said trailing end;
- and
- rotating said spool and said roll to maintain tension in said web material, whereby said adhesive portion of said tab of adhesive tape is applied by said roll to an underlying convolution of said web material to secure said trailing end and to maintain tension in said web material.
Apparatus for winding web material onto a spool, said apparatus comprising:
- a source of web material to be wound;
- a first frame;
- means mounted on said first frame for rotating said spool about an axis to wind said web material onto said spool;
- a second frame;
- means mounted on said first frame for permitting said second frame to move toward or away from said axis;
- roll means mounted on said second frame for engaging an outermost convolution of said web material during winding onto said spool;
- means mounted on said first frame for moving said second frame on said means for permitting toward said axis to allow initial contact of said roll means with said outermost convolution and away from said axis to allow continued winding of said web material onto said spool;
- means for permitting said roll means to move away from said axis relative to said second frame;
- means for detecting the position of said roll means relative to said second frame as said web material is wound onto said spool;
- means responsive to said means for detecting for actuating said means for moving to move said second frame away from said axis as said web material is wound;
- and
- means mounted on said second frame for pressing said roll means against said outermost convolution during winding.
