General

The Merrow 70-Y3B-2 is designed with a stitch multiplier that is lever operated on demand. The stitch multiplier doubles the stitch count and is ideal for applications that require extra strength at the selvages of joined material. The Merrow 70-Y3B-2 industrial sewing machine from Merrow is the only sewing machine for butted seaming with aSTITCH MULTIPLIER built into the sewing head. The machine sews a 5/8” stitch. The stitch count can be doubled while the operator is sewing and is effective for processing loose weaves to higher densities fabrics. The Stitch Multiplier is a lever on the front of the machine that can be pressed to double the number of stitches sewn. The 70-Y3B-2 is the only butted seam sewing machine that has a STITCH MULTIPLIER built into the sewing head. Wide seams of joined fabric are weak at the edges (the selvages) and the 70-Y3B-2 addresses this by DOUBLING THE STITCH COUNT on demand to add strength to seams - when and where it’s needed. To double the stitch count, the operator simply presses the 70-Y3B-2’s STITCH MULTIPLIER LEVER while material is being sewn.

Application

The 70-Y3B-2 is ideal for applications where swaths of WIDE FABRIC are being joined. Wide can mean weak AT THE SELVAGES, but not when the 70-Y3B-2 is used. The same goes for processing LOOSE WEAVES or HIGHER DENSITY FABRICS. In fact, the 70-Y3B-2 should be used for any application that requires that strength be added to a seam on demand.
