Sewing Construction Filter Fabric with a Flat Seam




When a large construction company approached Merrow about joining one of the components in their green roofing system, we knew immediately the machine they needed. The problem: they needed a strong but flexible way to join dense weave, water permaeable filter material. The solution: the Merrow 70-D3B-2 LS. The 70-D3B-2 LS produces a permanent locked stitch (made with two threads) that can withstand the stress of being sandwiched between two layers of uneven material (soil and drainage fleece) without compromising the integrity of the seam or the permeability of the material. Merrow sewed off a sample of the actual filter fabric the client would be installing and shipped their 70-D3B-2 LS calibrated to sew flawlessly.
