Abstract
An adhesive take-up, metering and spreading unit, for bonding machines is truck-mounted so that it can be replaced without having to interrupt the operation of the plant, includes a plurality of rollers arranged in series, wherein a first rubber-clad roller takes up adhesive from a reservoir and transfers it to an anilox roller, from which the adhesive is taken up by a second rubber-clad roller, which transfers it to a film to be bonded. Each roller rotates at a higher speed than the preceding one, and the unit is fitted with members that regulate the distance between the rollers, and consequently the pressure that each rubber-clad roller exerts on the anilox roller, in order to meter the precise quantity of adhesive taken up and spread on the film. This characteristic allows even special adhesives, whose application is particularly difficult due to their viscosity characteristics, to be precisely spread and metered.
