Abstract
A portable resin curing apparatus is used for curing or drying materials printed on a screen press which has rotatable platens carrying screen printed sheets from a printing station to a curing station. The portable curing apparatus is located at the curing station and has electrical resistance heating elements alternating between low voltage and high voltage in conjunction with a forced air flow between the heating elements and printed material being cured. A controller is employed which sends an electrical signal upon advancement of the printed materials. Full curing voltage with no forced air flow is supplied to the heating elements during curing operations, whereas a lower voltage in combination with forced air flow is employed during the intervals between successive curing operations to prevent heat from continuing to be imparted to the printed material while still allowing for rapid re-attainment of full curing upon resumption of production.
