Centerbulb Ribbed: Used in expansion and contraction joints where movement is expected. Larger sizes can accommodate greater transverse and shear movements. This WIRESTOP design is the most versatile and can be used in many designs both above and below grade. Flat Ribbed: Used in construction and control joints where movement between members is not expected. Most commonly used in horizontal joints. Flat Dumbbell: Used in construction joints where little or no movement is expected or in expansion joints of 1" or less in width. Generally used in horizontal joints above and below grade. Special configurations are available to meet the requirements of specific engineering firms andor government agencies. Spilt WIRESTOPS designed to eliminate split formwork are also available.

Paul Murphy Plastics produces quality extrusions for innovative projects. We were contracted by a customer in the automotive industry for a trim strip extrusion project to be used during assembly of a seat cover. The automotive seating supplier was looking for a way to locate two different fabrics on a seat cover and ensure proper placement of the seams during the adherence of the foam fill to the cover. Our solution was an innovative extrusion that could be sewn into the seam where the two fabrics joined. The part, measuring 0.900” wide x 0.100” long x 0.002” thick with varying widths and was made of custom blended polyolefin. To aid the sewing, we used a notching press to incorporate a notching pattern to precisely line up the fabric. Once the seat cover was sewn, the tab of the extrusion was used to adhere the foam to the cover of the foam bun. After the foam was adhered, a portion of the part was torn off, leaving a finished seam and seat cover. The final product went through various inspections to confirm the profile dimensions and verify the straightness over the length of the extrusion. We also performed destructive testing to verify the tear-off feature. Our part met FMVSS and AIAG requirements.
