  • Machine and method for assembling pleated filter material and a hollow core member
    Patent number: 4626307
    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.
