Abstract: Web lifter and/or stabilizer and method of lifting and/or stabilizing a travelling web and for coating a web. The device creates a web hold down force via a negative pressure slot at its exit side, which draws the web down against the surface on the entry side. The device can be actuated to move the web relative to a slot die coater off the die lips and stop the application of slurry to the web, thereby creating uncoated regions on the web surface. The device can then be actuated to move the web back into contact with the coater to start the application of slurry to the web, thereby creating coated regions on the web surface. Web lifting can be accomplished by rotating the device in first and second directions to lift the web off of the slot die coater and return the web back into contact with the coater.

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.

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.

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 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.

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.
