Apparatus for feeding a web of material from a supply thereof through an inspection area and winding the web, comprising a frame, a supply roll on the frame, a mandrel for winding the web on the frame having a gripper for gripping a leading end portion of the web, a drive for rotating the mandrel for winding the web thereon and for feeding the web through the inspection area, a panel engageable with the leading end portion of the web for backing the web fed through the inspection area, a pivotal connection mounting the panel on the frame for movement between an operative position relative to the mandrel for starting the winding of the web and a retracted position away from the mandrel, the panel being engageable with the leading end portion of the web, and cylinder units attached to the panel for moving the panel between operative and retracted positions. The gripper comprises a series of holes in the periphery of the mandrel and a vacuum pump in communication with the holes for drawing air into the mandrel. The panel when moved to operative position moves the leading end portion of the web toward engagement with the mandrel for being vacuum gripped, and when in retracted position enables rotation of the mandrel for the feeding of the web through the inspection area.
