CROSS WEB LAYER APPLICATION DEVICE

摘要

A device (10) for applying spaced layers (8) generally transversely across an elongate web (11) which defines a through path for the web (11) including parallel inlet and outlet path portions (14 and 16) spaced sideways from each other and a transverse path portion (20) between adjacent terminal and beginning ends (15 and 18) of the inlet and outlet path portions (14 and 16). The web (11) is moved lengthwise at a predetermined speed in a first direction along the inlet and outlet path portions (14 and 16), the device (10) periodically moves the portion of the web (11) along the transverse path portion (20) generally edgewise in a direction parallel to the first direction and at about the predetermined speed to essentially stop longitudinal movement of the position of the web (11) along the transverse path portion (20); and the device (10) applies a layer of material (8) such as tape generally transversely across the portion of the web (11) along the transverse path portion (20) as it moves tangentially by the periphery of a rotating applicator drum (21).
