Abstract: 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 of a wide printed web at intermittent periods to obtain accurate folding. The gripping apparatus is opened and closed by an endwise shifting of an actuator. A cam at one end causes the actuating member to shift 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 aft movement to a movable gripper jaw. There is no arcuate swinging of a rod such as in previous devices and hence there are no adverse effects of torque or twisting occuring during the gripping operation. The present construction permits uniform gripping of the full width of the printed web without any tendency of the operator member to twist and irregularly grip the web.

Abstract: A folding device for printed continuous webs moving at a high rate of speed. The device includes a pair of cooperating rolls between which the web passes. The rolls carry "working boxes" on the surfaces thereof to perform various folding functions on the moving web. Here the function of concern is the gripping of the web. An element on one roll causes the web to be pushed into open gripping elements on the cooperative roll. A bight is formed in the web at the position of gripping. During the concurrent rotation of the rolls the grippers close on the formed bight. Subsequently it is desired to remove the bight from the opening gripping elements. Simultaneously with the opening of the gripping elements there is provided a positive means for raising the formed bight out of the scope of the jaws. This bight stripper prevents any unnecessary entanglements of the fast moving printed web with the gripping elements during the folding of the web.

Abstract: A continuous paper web is fed in a longitudinal path. Glue is applied in transverse strips at regular intervals along the longitudinally disposed continuous web over a part only of the width of the web. A first plow folds over a portion of the web having the transverse glue strips to a position above an adjacent flat portion of the web. An insert or stuffer is fed into the web between the folded over portion and the flat portion and against an inner crotch thereof formed by the fold line. The space between the folded over portion and the flat portion away from the fold is open and forms a wide mouth to readily receive the inserts delivered thereto. This first folded over portion is then closed down over the inserts lying on the flat portion causing the glue strips to seal onto the flat portion. The folded over portion and the flat portion of the web contain inserts between each of the transverse glue strips.

Abstract: An apparatus for the printing industry in which a web tucker and cutter on one operational roller engages a combination gripper means and anvil on a cooperative operational roller to cause a bight of a printed web to be inserted into the gripper means and simultaneously to effect a severing of the bight portion so that the gripper means engages the severed ends of the web for subsequent folding in the making of a booklet.

Abstract: The utilization of a plurality of cooperating cylinders with externally mounted, adjustably attached universal box elements optionally containing either tucking, gripping, cutting or anvil devices to effect a folding and cutting of a multiple page booklet from a continuously printed web.

Abstract: A plow for use in a machine in the printing industry to provide for the folding of a paper web thereover. The plow through its novel mounting structure in the machine may be adjustably positioned relative to a frame support throughout a wide range of movements in all directions to accommodate any desired paper web travel through the machine. Adjustment of the plow position may be made while the paper web is moving through the machine to insure the proper and accurate guiding of the paper web through the machine.

Abstract: A bender and shaper for die cutters and perforators for the printing industry. The die cutters and perforators are generally an inverted "T" shape with the center leg of the "T" constituting the knife or perforator. The bender grips the side flanges of the "T" and with a swinging arm causes the cutters or perforators to be bent around the circumference of the wheel members employed to grip the side flanges. Various desired shapes of die cutters and perforators may be made without distortion of the cutting or perforating edges.
