Description

Kansai Special SQ7803LR-P Feed-Off-The-Arm Lap Seaming Machine

Heavy-duty industrial three-needle feed-off-the-arm double chainstitch sewing machine designed for lap seaming, side seams, inseams and other overlapping seam operations on medium-to-heavy-weight materials. The Kansai Special SQ7803LR-P is particularly suitable for denim, jeans, workwear and heavy garment manufacturing.

The machine features a square-type feed-off-the-arm construction that allows efficient handling of tubular and heavy garment components. Its three-needle configuration produces strong and durable double chainstitch seams, while the left-and-right differential feed mechanism helps reduce material slippage and ensures accurate alignment when sewing multiple layers.

The SQ7803LR-P is equipped with Kansai Special’s original belt-type rear puller, providing powerful and stable material feeding. This system is especially effective when sewing thick cross seams, crotch seams, yoke seams and overlapping sections commonly found in jeans and workwear production.
