A 卷边机 with a foot pedal is a standard setup in the mattress industry—designed to give the operator full control over the sewing process while keeping their hands free to guide the mattress.
Heavy-duty industrial sewing machines – These are designed for stitching thick materials. Brands like Juki, Consew, and Singer make machines suitable for mattress manufacturing.
Walking foot sewing machines – These machines have a special foot that helps feed thick or multiple layers of material evenly, which is important for mattress work.
Double-needle machines – These machines can sew parallel lines of stitching at once, which is useful for adding strength and aesthetic appeal to mattress seams.
