Abstract
Directed to a device for spreading an adhesive uniformly across a strip material comprising a container for strip to be coated, a pressurizable container for holding the adhesive, which is preferably a thermo-setting epoxy, a flexible tube connecting the adhesive container to an applicator head leading through a positive displacement meter. A feeder roll actuated by withdrawal of strip from the device operates the meter such that adhesive is applied only when strip is being withdrawn. The applicator head is provided with a slot through which adhesive is supplied from the interior of the applicator.
