Abstract

916,406. Coating fabrics. BEIERSDORF & CO. A.G., P. July 18, 1961 [July 20, 1960; Dec. 5, 1960], No. 26064/61. Class 140. Apparatus for the preparation of: self. adhesive tapes comprises a mixer for the ingredients of the adhesive composition, an extruder for extruding the adhesive, a heated slot die connected to the extruder and means for guiding flexible backing material in sheet or tape form adjacent the die. In the arrangement shown a heated screw extruder 1 has a feed-hopper 2, an extruder element 3 and a preferably heated slot die 4. Guide rolls 6<SP>1</SP>, 6<SP>11</SP> for backing material 5 are provided below the die 4. Preferably the lower part of the slot die is formed as an applicator for the adhesive composition. Thus in Fig. 2, slot die 11 has a central slit 12 terminating in a recess 13 bounded by lips 14, 15, the lip 15 acting as a doctor knife to control the thickness of the adhesive layer.
