Abstract: A machine for re-inking printing ribbons for line printers and the like includes a pair of spaced apart spool mechanisms which receive the supply and take-up spools of the ribbon. Disposed between the spool mechanisms is an inking roller which is partially submerged in an ink tank. Adjacent to the tank is a light source and light pipe assembly for detecting holes in the ribbon to be inked. The device accommodates ribbon spools of differing lengths, and is also provided with a ribbon edge sensor which controls the axial position of the ribbon as it is wound onto one of the spools. The spool mechanisms drive the ribbon past the hole detector in one pass, and a pressure roller urges the ribbon onto the inking roller in another pass to re-ink the ribbon.

Abstract: Typing ribbons stored in cartridges are reinked by the use of an apparatus having a plurality of drive devices arranged to pull the ribbon through the reinking mechanism and return the ribbon to the cartridge without placing stress on the cartridge case or rewinding mechanism. The apparatus includes a bracket for securely mounting the cartridge with the ribbon threaded over a self-inking drum. A drive system is provided for rotating the inking drum and pulling the ribbon by a drive capstan to maintain a taut condition. A variable speed motor is included for returning the ribbon to the cartridge through its reloading mechanism. Sensors and an electrical control circuit are provided for automatically stopping the reinking process at its completion or if a defect in the ribbon is detected.

Abstract: Liquid is applied to absorbent material, preferably menthol solution to foil-backed paper for use in packaging menthol cigarettes, in uniform and controlled manner.

Abstract: A method is disclosed for coating a substrate or web with a plastic material. A liquid plastisol coating is applied to the web and the coated web is then passed between a put-on roll and a heat drum, which heats and cures the plastisol. The put-on roll is pressed against the heat drum to compress the coated web. The plastisol is partially cured to gelation while being compressed by the put-on roll, and the curing of the plastisol is completed during further travel of the web around the heat drum.

Abstract: The subject matter of this specification pertains to improvements intended to be utilized in a ribbon inking machine having a frame, a drum mounted on the frame, a carriage movably mounted on the frame so as to be capable of being used with respect to the drum, a ribbon feed roller mounted on the carriage, a ribbon inking structure mounted on the carriage, and a ribbon takeup roller mounted on the frame. Such a machine is preferably constructed to include a pressing element mounted on guide rods so as to be capable of being moved towards and away from the drum. Solenoids are used to control the tension on bands mounted on the pressing element and passing around the guide rods. When they are tightened they hold the pressing element relative to the guide rods. A mechanical mechanism provided for raising and lowering the pressing element is located on the guide rods.

Abstract: An apparatus for applying a stripe to the surface of a continuous strip of film material. The film is drawn from a roll of film wound on a supply reel and through a striping station where a striping material is applied to a predetermined zone on the upper surface of the film. Next, the film is drawn around a plurality of drying rollers which are positioned to form a generally rectangular, inwardly spiraling drying path. The film with the dried striping zone is collected on a take-up reel which is motor driven in co-operation with a drawing roller. The drawing roller draws the film from the supply roller, through the striping station and around the drying path.

Abstract: Substrate supply and windup rolls are arranged in a housing arranged at each end of a vacuum coating chamber. Gate means provide for optionally sealing of one housing for loading and unloading purposes while simultaneously coating a continuous strip related to the supply and windup rolls of the second housing. Carriage means carry tension rolls at the extreme ends thereof and reciprocate across the coating chamber in operative association with said housings at the extremes of the reciprocating movement whereby to effect the coating and loading or unloading operations.

Abstract: An improved ribbon re-inking apparatus having an improved means for holding and recirculating the re-inking composition comprising means for feeding and collecting the ribbon, means for driving the collecting means, inking means for applying re-inking composition to the ribbon, guide means for guiding the ribbon into contact with the inking means, and a supply means for providing a continuous supply of re-inking composition to be picked up and transfer to the ribbon, which supply means broadly comprises a closed reservoir means which holds a supply of re-inking composition, a relatively shallow open feed container which holds a pool of the composition to be picked up, a pump for continuously pumping the re-inking composition between the reservoir and the feed container, and a filter means for filtering the re-inking composition.

Abstract: An apparatus for reinking ribbons, including computer ribbons, comprising means for feeding the ribbon to be inked; means for collecting the reinked ribbon; drive means; guide means; inking means for applying a reinking composition to the ribbon so that it can be reused to print, including a reinking composition supply reservoir, a feed or ductor roller and an inking roller, wherein the positional relationship between the feed and inking roller determines the amount of reinking composition transferred from the reservoir to the ribbon; and cam means for adjusting the positional relationship between the feed and inking rollers.
