摘要:
A compact filter element and a method for sealing an end thereof are provided. The compact filter element includes a filter material formed into a winding and an adhesive element, having a predetermined size and shape, that fixes an outer end portion of the filter material to an outer side portion of the filter material. The adhesive element provides improved control of the amount of adhesive applied to the filter element, because the adhesive element has a predetermined amount of adhesive. Thus, the costs associated with the adhesive process can be reduced, by minimizing excessive use of adhesive. Also, the process of applying the adhesive element is a faster process and requires less expensive equipment to implement than a hot melt process.
