    摘要： A web edge sensing and guiding system in which a travelling web exits from a tiltable web guide apparatus in a plane transverse to the plane of motion of the web guide apparatus. The lateral position of the web edge is sensed at the exit side of the web guide apparatus and means are provided for moving the web edge sensor along a path to substantially follow movement of the exiting web in a direction perpendicular to its plane while maintaining the web edge sensor at a substantially uniform spacing laterally of the longitudinal path of travel of the web to thereby accommodate fluctuation of the exiting web in a direction perpendicular to its plane caused by tilting of the web guide apparatus in its plane of motion.

    摘要： A web guide apparatus having swingably mounted arm assemblies for supporting a web guide roller for shifting movement in a direction crosswise of the path of web travel, in which the arm assemblies include a main arm swingably mounted on a stationary support and an auxiliary arm swingably mounted on the main arm, and mechanism for effecting swinging of the auxiliary arm relative to the main arm through an angle correlated with the angular movement of the main arm relative to the stationary support to move the roller in a path having a relatively flatter curvature than the arc defined by the main arm during its angular movement.
