CAM OPERATED GRIPPERS FOR PRINTED WEBS ABSTRACT OF THE DISCLOSURE An apparatus for the printing industry relating to the folding of printed webs. More particularly the invention concerns the means for uniformly gripping the full width Or a wide printed web at intermittent periods to obtain accurate folding. The gripping apparatus is opened and closed by an endwise shifting or an actuator. A cam at, one end causes the actuating member to shirt one way and then a cam at the other end shifts the actuating, member in the other direction. The actuator member is itself cammed to move fore and aft as it moves endwise and imparts only its fore and art movement to a movable gripper jaw. where is no arcuate swinging or a rod such as in previous devices and hence there are no adverse ef- fects of torque or twisting occuring during the gripping oper- ation. The present construction permits uniform gripping or the full width of the printed web without any tendency Or the operator member to twist and irregularly grip the web.
