Abstract: A paper coater includes a frame, an entry guide roll and an exit guide roll both carried by the frame and along a path of travel of a continuous paper sheet. The paper coater includes independently controllable hot wax applicators carried by the frame between the entry and exit guide rolls. Each independently controllable hot wax applicator includes a press roll, an engraved applicator roll opposite the press roll so that the continuous paper sheet is therebetween, and with the engraved applicator roll extending into a hot wax reservoir to pick up hot wax. Each wax applicator includes a doctor blade adjacent the engraved applicator roll to control a thickness of hot wax. At least one selectively operable positioner relatively moves the press and engraved applicator rolls between active and idle positions. The paper coater provides different wax application rates and can be reconfigured relatively quickly between different application rates.

Abstract: A cap sheet metal (and pivot sheet metal) is configured to be able to move linearly with a cap arm (and an arm stay) via engagement between an engagement hole and a fitting shaft. Furthermore, the cap sheet metal (and the pivot sheet metal) can move pivotally with respect to the cap arm (and the arm stay) using the fitting shaft, which engages with the engagement hole, as a pivotal shaft. Thus, even if, for example, the direction of biasing toward the applying roller deviates or a positional relationship with the applying roller deviates slightly, the liquid holding member moves and pivots in the bias direction depending on the deviation. As a result, the contacting pressure of a contacting portion on the applying roller can be made uniform.

Abstract: This liquid applicator covers all sides of substantially flat and dimensional surfaces of boards or siding with stain or paint in a uniform manner. The applicator has an upper and lower series of rollers and wiping agents, a set of vertical rollers, and a paint collection assembly. Preferably, some of the upper rollers and some of the lower rollers will consist of horizontal wet-rollers which receive liquid from an outside source. The remaining rollers are horizontal dry-rollers which absorb, smooth and buff the surface. The vertical rollers coat the side aspects of a board. All rollers spread paint rapidly over all board surfaces in a uniform manner. The main components have adjustment features: the rollers move vertically and toggle clamps and the like permit custom selection and sizing for each of the rollers and wipers. A catch pan has a drain plug at or near its lowest point.

Abstract: A roll coating system for coating strip metal having a plurality of coating head rolls mounted on support sleds capable of linear translation along a single rail. Precision linear actuators are located between each support sled and between one of the sleds and a fourth sled. A splice traverse mechanism actuated by a piston/cylinder displaces the fourth sled. Each of the rolls can be independently displaced or the entire head can be displaced by the splice traverse mechanism. Force measurement sensors are located in the support sleds for an accurate measurement of nip pressures between the respective rolls. The elastic response of the support sleds may be varied to alter the natural resonant frequency of the coating system. The movement of a pan lift mechanism is coupled to the movement of the pickup roll so as to eliminate the chance for collision therebetween.

Abstract: A device for spreading a substance onto a moving web of material, which comprises an extrusion head and a rotating bar which is carried by a support member applied to the extrusion head near the outlet of a delivery slit. This latter has an inner profiled recess in which engage limiting blade segments which extend up to the outlet of the delivery slit in order to laterally limit the regions in which spreading is carried out. The rotating bar has its outer surface operatively contacting the web only in the regions in which the substance is spread, and it is recessed or interrupted where no spreading is wanted. This device allows to spread a substance onto a width of web reduced with respect to the width of the extrusion head, or even onto separate strips of the web.

Abstract: The invention relates to a method and to an apparatus for the production of stamp or photo album leaves with slip-in pockets for the stamps. Two transparent sheets in web form are linearly bonded to one another, and slip-in pockets are stamped out of the bonded sheet material to form double sheet pockets joined along a linear edge. The slip-in pockets are stamped out of the double sheet web by a stamping tool assembly in a predetermined arrangement corresponding to the pocket placement intended for the album leaf, and holds them firmly in this arrangement by a partial vacuum. In the meantime, an adhesive has been applied to the album leaf in the places provided for the slip-in pockets. The album leaf is then brought into contact with the slip-in pockets held fast by partial vacuum on the stamping tool so that the pockets are secured to the album leaf.

Abstract: A varnishing unit for applying varnish in a strip of selected width on a sheet carried on the impression cylinder of a printing press distinguished by use of a plurality of adjustable varnish blocking rollers arranged adjacent a fountain roller between a varnish trough and a metering nip formed between a metering roller and the fountain roller. The blocking rollers are hard surfaced and of relatively small diameter, and are secured to the frame by arms located at the respective ends of each roller. Each blocking roller is individually adjustable between (a) a position in which it forcibly indents the surface of the fountain roller so as to substantially cut off the flow of varnish to the metering nip, in the region of width controlled by the blocking roller and (b) a position withdrawn from the surface of the fountain roller to permit passage of a strip of varnish in the controlled region to the metering nip and thence via intermediate rollers to the varnishing cylinder.

A plurality of wick applicators may be provided with the spindle be mounted for rotation relative to each applicator which may be at predetermined radial distances from the spindle axis.

Abstract: Stiffeners in the form of spaced, narrow bands or lines of flowable, quick-setting material are applied to one side of a moving paper web to be used as computer paper. The stiffeners are applied either immediately before or during the time the paper web is partially wrapped around a cylindrical drum so that the material will set to a solidified condition while it is on the drum to set up a molecular pattern in each stiffener line, causing the paper web to be inherently biased in one direction. Guide means is provided for directing the paper web onto and off the drum. The material may be applied by applicator guns or wheels as the paper web moves through a rotary printing press and as it moves toward a line hole punch apparatus, perforating means and a fan-folding mechanism.
