ABSTRACT:
An automatic assembly machine for assembling a pleated filter material and a perforate hollow core member includes a wrapping station, an adhesive application station and a clamping station. A conveyor moves the filter material and the core member together as a unit through the wrapping station and the adhesive application station. The clamping station both clamps the seam to which adhesive has been applied for a period of time sufficient to permit curing of the adhesive joint, and simultaneously conveys the filter material and core member assembly. A method for assembling a pleated filter material and a perforate hollow core member includes the steps of conveying both the filter material and the hollow core member to a point where they come in mutual contact, supporting one of the members on the other, and simultaneously conveying the filter material and core member sequentially through a wrapping station and an adhesive application station. At the wrapping station the filter material is formed about the core member and the free ends of opposed end pleats are brought into juxtaposition. An adhesive material is applied to selected apposite surfaces at the adhesive application station. Following the application of adhesive material the apposite surfaces are clamped together for a period of time sufficient to permit curing of the adhesively joined surfaces and, simultaneously therewith, the assembled elements are conveyed as a unit.
