Abstract
A compact apparatus for curing an uncured resin impregnated in a filter element (12) having a uniform cross-section in the longitudinal direction, and for reinforcing the filter element (12). The apparatus includes a curing pot (38) formed of outer and inner tubes (40, 42) secured integrally and coaxially with each other to form an annular space (44) therebetween, having a cross-section similar to that of the filter element (12) to be treated, for accommodating the filter element (12) therein during the curing process. A hot air circulation mechanism for forcibly supplying hot air through the filter element (12) in the annular space (44) is provided so that the temperature of the filter element (12) is effectively elevated to a value at which the curing of the resin is completed. The curing operation can be sequentially carried out by intermittently displacing a holder (64) accommodating the filter element (12) therein to an operational position and transferring the filter element (12) into the curing pot (38).
