摘要:
An apparatus for drying tire cord fabric dipped in a liquid coating containing a vaporizable solvent. The drying chamber of the apparatus includes a boiling sump for filling the chamber with solvent vapor, and a plurality of vertically elongated plenums mounted in side-by-side relation, each plenum having a number of horizontally elongated nozzles in vertically spaced relation. The tire cord fabric is passed adjacent the nozzles and super-heated solvent vapor is forced through the nozzles against the moving fabric to flash off or vaporize the solvent carried by the fabric, thereby drying the fabric.
摘要:
A dip tank for holding liquid adhesive used for increasing the adhesion or bond between fabric and rubberized material used in the production of pneumatic tires. A rubber bag is secured adjacent the bottom of the tank and inflated and deflated to control the level of the liquid within the tank. A roller for directing the fabric into dipping relation with liquid in the tank, is disposed in fixed relation within the tank and journalled for rotation in a pair of bearings disposed in sealed relation outside the tank, such that the liquid cannot seep into the bearings and eventually wear them out or destroy them to hamper rotation of the roller.
摘要:
A pair of specially configured scraper blades mounted for rotating into and out of compressive wiping engagement with a fabric, previously dipped in a liquid coating, to remove excess liquid from the fabric. An air cylinder, or spring, is utilized to maintain curved lips of the scraper blades in predetermined compressive relation with the moving fabric.
