Abstract
Apparatus for splicing a replacement web to a moving web comprises a guide for guiding the moving web along a predetermined path. A cutter severs a portion of the replacement web to establish the leading edge thereof; and a splicing station is positioned in the path of movement of the moving web for splicing the leading edge of the replacement web to the moving web while the latter is moving. The splicing station, which is constructed and arranged to establish a lap joint between the leading edge of the replacement web and the moving web, comprises a delivery device that includes a splice strip having adhesive on one surface, a device for positioning the strip in a direction perpendicular to the direction of the moving web, and a device for moving the replacement web in a direction perpendicular to the direction of the strip and into engagement with the adhesive surface of the strip in such a way that about half the width of the strip is covered by the leading edge of the replacement web which adheres to the strip, and the other half of the strip is uncovered exposing the adhesive. Finally, a device is provided for moving the strip and the replacement web adhered thereto relative to the moving web such that the exposed adhesive on the surface of the strip engages the moving web which is thereby adhered to the strip.
