| 181 | Apparatus for attaching endsheets without moisture wrinkles | US568737 | 1995-12-05 | US5882469A | 1999-03-16 | Don E. Detterman; Carolyn S. Lambert; Jerald P. Danhoff; Jeffrey D. Habegger |
| A machine for attaching a book cover to endsheets within an adhesive is set forth. The adhesive is applied while it is within a predetermined temperature range. The machine includes a housing, an application roller journalled within the housing, and a metering roller journalled within the housing. The metering roll is axially parallel to the application roller and nearly contacts the application roller at a nip. The region above the nip defined by the application and metering rollers, and two internal seals with the housing is an adhesive reservoir. The adhesive remains in this reservoir before it is applied by the application roller. The machine also includes a level detector which detects the level of the adhesive in the adhesive reservoir. The level detector is coupled to a controller and produces a low level signal when the level of the adhesive is below a predetermined level threshold. Once this condition occurs, a transport means for transporting the adhesive from a main reservoir to the adhesive reservoir begins operation. A temperature sensor which measures the temperature of the application roller is also included. When the temperature of the application roller is below a predetermined range, heaters attached to the application roller begin operation. As such, the machine applies a hot melt adhesive within the appropriate temperature range consistently along the entire endsheets. | ||||||

| A rotary coater device (12) is provided, comprising front and rear frame plates (30) having mounted therebetween: a die bracket assembly (100), a screen assembly (200), a heater hood assembly (300), and an impression roll assembly (400). The die bracket assembly (100) includes (i) a die (500) positionable within a screen (202) and having an opening (550), the die being movable from an operating position wherein the die opening is proximate to an inner surface of the screen to an idle position wherein the die is drawn away from the inner surface; and (ii) a pivotable support arm (102a) fixedly attached at one end to a positioning mechanism (112) and removably attached at an opposite end to the die, the pivotable support arm being pivotable away from the screen when the opposite end is detached from the die to expose the screen for removal from the coater device. The screen assembly (200) supports the cylindrical screen in an operating axial position about a first axis (127), and includes (i) at least one guide wheel (206) engageable with the screen and (ii) a retractable support arm (238) pivotable about an axis (72) from a first position wherein the at least one guide wheel is engaged with the screen in the operating axial position, to a second position wherein the at least one guide wheel is disengaged from the screen. The heater hood assembly (300) assures an evenly heated outer surface of the screen. The impression roll assembly (400) includes an impression roll (402) which provides a backing for a web to be coated by the coater device. | ||||||

| A hot melt material coating system (10) is provided, comprising (i) a rotary coater (12) driven by a motor (604); (ii) a rotary coater position, speed and direction indicator (610) operatively connected to the rotary coater and providing a signal representing the position, speed and direction thereof; (iii) a web position, speed and direction indicator (612) operatively connected to the web and providing a signal representing the position, speed and direction thereof; and (iv) a control system (600). The control system (600) includes (a) a first control circuit (614) for receiving the rotary coater position, speed and direction indicator signal and the web position, speed and direction indicator signal, and for outputting a control signal to the motor in response to the indicator signals to maintain a predetermined relationship of the position, speed and direction of the rotary coater with respect to that of the web; (b) a web position indicator (618) positioned proximate to the web and providing a signal representing the position thereof with respect to the web; and (c) a second control circuit (616) for receiving the web position indicator signal and the web position, speed and direction indicator signal, and for outputting a web position correction signal to the first control circuit, the first control circuit varying the control signal in response to the web position correction signal. | ||||||

| 185 | Apparatus for applying fluid, pasty or plastic substances to a substrate | US478213 | 1990-02-09 | US5122219A | 1992-06-16 | Volker Ludwig |
| In a method of applying fluid, pasty or plastic substances, especially thermoplastics, to a substrate, the substance is melted, heated and applied via an outlet slit of a perforated cylinder to the substrate, the substrate then being lifted off from the cylinder. Provision is made here for the cylinder (3) to be connected to an energy source (17) and to be designed itself as a heat source for the substance. | ||||||

| Apparatus and process for applying a flowable substance to a substrate. A perforated cylinder feeds the flowable substance to the substrate with a counter-pressure roll adjacent. A lift-off roll assists in drawing the substrate off the cylinder in response to the degree of adhesion between substrate and cylinder. The distance between the axes of rotation of the counter-pressure roll and cylinder is less than the sum of radii of the roll and cylinder. | ||||||
| 188 | Method of making gaskets and products formed thereby | US25019372 | 1972-05-04 | US3890183A | 1975-06-17 | FARNAM ROBERT G |
| A gasket having improved sealing properties and the method of forming such a gasket wherein a continuous strip or web of gasket material is wound on a core with the core having a crosssectional configuration corresponding to the internal configuration of the gasket being made. The web material is wound upon itself and, in the preferred embodiment, has a series of intermediate bonding layers of a fluid-impermeable polymer material which in the end product form a plurality of parallel fluid barriers to produce effective sealing. The winding of the web material on the core and the application of the polymer material to the web provides a tube which is then cut into preselected thicknesses to provide individual gaskets. Additional polymer material may be provided on the cut or exposed surfaces of the gasket is desired. The cross-sectional flange width of the gasket is dictated solely by the convolute gasket material and the polymer material layer or layers. One aspect of the improved method consists in preparing a roll of the gasket material which is to be wound on the core with the base material having applied to one or both sides thereof an adhesive coating which has been dried, at least to the extent that it will not adhere or cohere to itself when rolled upon itself, before the tube is formed. The coatings on the prepared roll may be individually tailored to provide a very thin coating on one side and a relatively thicker coating on the other side which are substantially dimensionally stable when applied to the web and when the prepared material is formed into convolute tubes.

| The adhesive roll of a single facer machine and/or the adhesive rolls of a glue machine at a double facer are heated to a surface temperature of between 130*F and 150*F by circulating water to heat the starch adhesive to a temperature just below its gelatinization temperature so long as the rolls are rotating.
