1,158,740. Coating with glue. METAL CONTAINERS Ltd. 2 April, 1968, No. 15824/68. Heading D1L. A reactive-curing glue is applied by a stereo-roller 5 to a sheet 6. In order to prevent cobwebbing of the glue on the applicator, it is supplied to counter rotating rolls 1, 2 moving at differing speeds which thus shear and mix the old and new glue. Metering pumps 21, 22 dispense the reactive ingredients to a mixer 16. The rollers 1, 2 are internally heated. |
