Abstract
A multipart underlayment having a cap sheet and base sheet combined to form a pocket for securely holding building materials and environmentally-friendly manufacturing method for manufacturing the same.
Claims13
A method of manufacture of a multi-part underlayment comprising a base sheet and a cap sheet that are combined to create a double layer hinge section as well as a single-layer nose section extending from the cap sheet, creating a pocket for holding flashing, the method comprising:
- producing the base sheet by:
- providing a carrier support sheet contained on a first base sheet roller;
- feeding the carrier support sheet through a series of rollers configured to place the carrier support sheet under tension;
- coating the carrier support sheet in a pressure sensitive adhesive;
- cooling the carrier support sheet;
- applying a base sheet release liner held by a second base sheet roller to the carrier support sheet;
- sizing the carrier support sheet to a predetermined size using at least one pair of base sheet sizing rollers creating a newly formed base sheet;
- and
- winding the newly formed base sheet on a base sheet winding roll;
- producing a cap sheet by:
- providing a second carrier support sheet contained on a first cap sheet roller;
- feeding the second carrier support sheet through a series of rollers configured to place the second carrier support sheet under tension;
- coating the second carrier support sheet in a pressure sensitive adhesive;
- cooling the second carrier support sheet;
- applying a cap sheet release liner held by a second cap sheet roller to the second carrier support sheet;
- applying a temporary cap sheet release liner held by a third cap sheet roller to the second carrier support sheet;
- sizing the second carrier support sheet to a predetermined size using at least one pair of cap sheet sizing rollers creating a newly formed cap sheet;
- and
- winding the newly formed cap sheet on a cap sheet winding roll;
- producing the multi-part underlayment by:
- feeding the base sheet held on the base sheet winding roll through a series of rollers configured to place the base sheet under tension;
- stripping the cap sheet held on the cap sheet winding roll of its temporary release liner using a temporary release liner recovery roller to recover the release liner;
- combining the cap sheet with the base sheet under pressure using at least one pair of final product sizing rollers creating a newly formed multi-part underlayment;
- and
- slitting the newly-formed multi-part underlayment into desired widths.
