CONTINUOUS-ACTION DOUBLE-BAND PRESS Russian patent published in 1996 - IPC

FIELD: manufacture of edge plastics used in furniture industry. SUBSTANCE: the double-band press has a bed, assembly of steel bands installed on roller supports with radial seals, steel band drives, lubricant source pneumatically connected to the cavities of pressure pads, having metal plates with longitudinal and lateral grooves evenly spaced on their planes, in which stationary supporting strips are installed. The groove is made along the contour of the pressure pads; a shaped frame with a seal edge secured on it is installed on a round-section rubber collar for its vertical movement. The stationary supporting strips and sealing frame are made of the same antifriction material. The metal plate is furnished with additional detachable supporting T-shaped strips installed at the inlet and outlet of the bed steel band assembly. The T-shaped frame and supporting strips are two-layer ones; their sealing edges facing the band are made of polymeric material, for example, a compound based on sealing fluoroplastic with addition of carbon. The lubricant source is made as a fog lubrication generator, it is additionally connected to the groove along the contour of the metal plate. The radial seals of the roller supports of the steel band drums drive are adjustable, they have a back nut, two rings, with a collar in the form of a set of chevron members of polymeric material and a pressure member in the form of a spring ring or pressure bush placed between them. EFFECT: improved design. 4 cl, 10 dwg
