Abstract: A glue applicator for a labeling machine has the customary glue roller rotating about a vertical axis. A scraper blade is held adjacent the periphery of the roller to remove excess glue from the roller so that a label to which glue is transferred from the roller will not receive a coating of more than desirable thickness. Relatively small blade inserts provide the sharpened edges for scraping the excess glue from the roller. A support member is mounted to a carrier that swings about an axis parallel to the axis of the roller. The blade insert is clamped against the support member by means of a clamping member whose clamping force is developed by bolts that pass through the clamping member and are threaded into the support member. Eccentric elements are provided for adjusting the support member and, hence, the blade insert carried thereon to achieve a uniform and accurate gap between the scraping edge of the blade insert and the periphery of the roller.

Abstract: Solder paste is automatically applied to circuit boards, in predetermined amounts at predetermined positions by providing a plurality of holes in a nylon, "Delrin," "Teflon" or other plastic-metal plate, the holes being in a predetermined pattern, filling solder paste into the holes which are facing in an upward direction pivoting the plate over the circuit board, and ejecting the solder paste onto a circuit board. Conveniently the solder paste is ejected by pins mounted on a further plate and reciprocated in the holes. The position of the pins in the holes during filling determines the amount of solder paste filled into the holes.

Abstract: A vibration damper for use with an apparatus for applying liquid to both sides of a running web and then drying the web with an air drier. Vibrations induced by the air drier are damped by uniformly blowing air on both sides of the running web between the drier and the liquid application heads. Preferably, the gas ejection surfaces are stepped or tapered so allow larger vibration near the drier but to reduce the allowed vibration nearer the liquid application heads.

Abstract: The applicator roller (2) can be driven in both directions of rotation. For coating the web of material (3) in the counter-directional mode, a distributor roller (6) is brought up to the applicator roller. In that way it is possible for the film of liquid (1) to be taken from the same reservoir zone (5) as in the co-directional mode of operation. That saves shifting the metering roller (4) which remains at the same position both in the co-directional mode and in the counter-directional mode of operation.
