  • Patent number: 10106363
    Abstract: A flap folding arrangement is disclosed. The flap folding arrangement includes an axially extending rim that initially contacts a flap of a product to partially fold the flap as the product is dropped from a feed conveyor into a first pocket of a rotator pan. A controller is adapted to rotate the rotator pan away from a first position which drives the flap into contact with a flap-folding flange and a radially extending rim until the product is positioned at a second position under a flap-folding gate. The controller is adapted to drive a product discharger into contact with the product to drive the product out of the first pocket and away from the folding assembly after rotation of the rotator pan.

    Abstract: A method is provided for applying adhesive to the flutes of a corrugated sheet web. An applicator roll is provided with a uniform thin coating of adhesive by a metering rod. Exposed crests of the flutes are brought into contact with a coating of adhesive that has been applied to a surface of an applicator roll in order to provide a uniform bead of adhesive on the flute crests. The flutes are compressed against the applicator roll surface in a forward direction relative to the direction in which the web is moving adjacent the applicator roll surface. In one embodiment, the applicator roll has a surface linear velocity greater than the speed at which the web is traveling.

  • Patent number: 7445693
    Abstract: Two axially parallel rolls are pressed against each other in a device for producing and/or treating a moving material web. Sensor elements are arranged in the force transmission path running from the force-producing elements via the rolls, outside roll bodies of the two rolls. As a result of displacing the sensor elements out of the roll bodies of the rolls, the production of the rolls is less complicated and less expensive. No sensors have to be embedded in the roll bodies, which opens up the possibility of using standard rolls. In addition, the occasional grinding of the rolls can in this way be performed without any regard to the sensor elements. Nevertheless, the pressure prevailing between the rolls can continue to be measured directly, since the sensor elements are arranged in the transmission path of the pressing force.

  • Patent number: 6485567
    Abstract: An external electrode forming apparatus is used to form external electrodes on the component chips. The external electrode forming apparatus comprises a component conveyer belt, a belt feeding mechanism, a component-inserting machine, a component-reversing machine, a paste-coating machine, and a component-discharging machine. For the component-inserting machine, the component-reversing machine, and the component-discharging machine, pressure pins are used to insert or move the component chips. These pressure pins have at the tip part a taper portion with a tip shape smaller than that of the component holding hole. Since the pressure pins of this type are used, the tip portions of these pressure pins may be prevented from impinging upon the opening edges of the component holding holes, and the pressure pins after the impingement may be hindered from forcibly being inserted into the component holding holes, whereby damage to the interiors of the component holding holes can be extremely diminished.

  • Patent number: 6399160
    Abstract: A method and apparatus for coating a paper or board web, wherein the web to be coated is brought to a film transfer coater and taken to a nip between the film transfer roll of the coater and its backing roll, and coating mix is applied onto the surface of the film transfer roll. The web is taken through the nip between the rolls and the rolls are turned, whereby the coating mix applied onto the applicator roll is at least partly transferred onto the surface of the web. The web is supported through the nip by means of a belt traveling at the same speed as the web, the belt having been arranged to travel on the backing roll. The web is taken onto the surface of the belt prior to the nip and separated from the belt after the nip, and it is pressed against the film transfer roll by means of the belt. The length of the path where the web and the film transfer roll are in contact with each other is controlled by varying the position of the web and the belt.

  • Patent number: 5057337
    Abstract: A pair of solder coating rolls are disposed horizontally adjacent one another for rotation about parallel horizontal axes, and are spaced apart to define a narrow vertically-oriented nip therebetween for accommodating a lead frame therein. Lower parts of the rolls contact a solder bath, and counter rotation of the rolls carries the solder upwardly on the periphery of the rolls to create a small pool of solder at the upper end of the nip. The lead frame is driven vertically upwardly through the nip, which nip has a minimal dimension greater than the lead frame thickness. The lead frame is driven vertically upwardly at a linear speed which is different from, and preferably slower than, the peripheral speed fo the solder coating rolls. This enables preheating of the surface of the lead frame due to its longer exposure to and contact with the hot solder which coats the periphery of the rolls, thereby improving the wetability of the lead frame surface.

  • Patent number: 4601256
    Abstract: An apparatus and method for applying a smooth uniform coating to a web (W) having variations in thickness and density and surface irregularities is disclosed. The invention includes a vertical floating pressure table (B) which supports the traveling web (W) against a transfer roll (20) and a scrape blade (46). Coating material (C) metered by a doctor blade (34) is applied to the transfer roll (20) at (40) and then applied to the web in a uniform layer (78). The pressure table (B) is supported against the web by a counter-balancing linkage arrangement (D) which maintains a constant uniform pressure on the table (B) and web (W) regardless of the vertical movements of a table platform (60) in response to web variations an irregularities. A smooth uniform coating (80) is provided.

  • Patent number: 4294187
    Abstract: A paint applicator for direct roll coating of textured panels or sheet-like members comprises a core, a layer of fibrous web material disposed over the core, a protective plastic tube member disposed around the layer of fibrous web material, and a layer of woven material disposed over the protective tube member. The fibrous web allows for uniform application of the paint film due to its softness and ability to follow contoured surfaces. The protective tube member prevents paint from penetrating the fiber web. The woven material carries the paint on the roll applicator.

  • Patent number: 4235189
    Abstract: Apparatus for applying bronze powder to adhesive-coated portions of one side of a running web of cigarette paper has a magazine for a supply of bronze powder and a feed screw which draws powder from the magazine and delivers some of the withdrawn powder into a chamber for a transfer wheel whose peripheral surface applies powder to the one side of the web. The powder which fails to adhere to the web is returned into the helical groove of the feed screw upstream of the chamber. A cylindrical sleeve which surrounds the feed screw has an outlet located downstream of the chamber and serving to return into the magazine such powder which is transported beyond the chamber. The sleeve has a longitudinally extending slot for a brush whose bristles extend into the helical groove of the feed screw to prevent agglomeration of powder in the groove.
