DEVICE FOR MANUFACTURE OF HONEYCOMB PACKS Russian patent published in 1994 - IPC

FIELD: manufacture of honeycombs. SUBSTANCE: device has heating unit to ensure full curing of adhesive strips of material sheet; the first and second material unreeling members made in form of cassette units and provided with three guides. Guides are made in form of combs or grooved rollers. One guide is located after the first cassette unit, the second guide is arranged after the first adhesive application unit, and the third guide, after the second adhesive application unit. Cassettes with wound-on tapes having width equalling three widths of faces of cell of honeycomb are arranged in each cassette unit so that tape edges in adjacent cassettes are spaced at distance equal to width of face of cell of honeycomb. Cassettes of the first unit are displaced relative to the second cassette unit so that tapes overlap one another through width of face of honeycomb cell. Spacing of combs or grooves in guide rollers for accommodation of material tapes of respective cassette units equals four widths of faces of honeycomb cell. Bands of adhesive-application roller of the first adhesive-application unit are spaced at distance equal to two widths of faces of honeycomb cell and made coincident with edges of tapes coming from the first cassette unit. Bands of adhesive-application unit are disposed against the middle of lower tapes of sheet with spacing equal to four widths of faces of honeycomb cell. Upper roller of material sheet formation unit has holding down means, and its lower roller is heated. The second cassette unit is arranged after the first adhesive-application unit, and disposed after the second cassette unit are located material sheet formation unit, heating unit for full curing of adhesive, and the second adhesive-application unit. EFFECT: higher efficiency. 4 cl, 11 dwg
