Senior 300U Heavy-Duty Automatic Mattress Tape Edge Machine

Description

Senior 300U Heavy-Duty Automatic Mattress Tape Edge Machine

Specialized industrial mattress closing and perimeter-binding workstation engineered for taping and closing multi-layered mattresses, box springs, and thick futon pads. The Senior 300U incorporates a heavy-duty 300U-style chainstitch sewing head mounted on a motorized carriage with a variable-angle support arm, operating alongside an automated rotating/conveyorized mattress worktable. As the sewing carriage traverses around the perimeter of the mattress, an integrated tape-folder binder feeds and wraps edge binding tape over the raw border seam, locking top and bottom quilted ticking panels directly to the border side-wall in a single, high-tensile pass.

The sewing head utilizes an alternating walking-foot compound feed mechanism and a dual-thread chainstitch looper to sew through thick, high-loft foam, memory foam, latex, and inner-spring spring casings without skipped stitches, needle deflection, or fabric shifting. Operators can adjust the head angle, sewing height, carriage travel speed, and table lift via an intuitive control console to accommodate mattresses of varying thicknesses (from slim toppers to deep pillow-top luxury mattresses). Equipped with automatic corner deceleration and smooth track tracking, the Senior 300U ensures tight, uniform corner turns and dependable, clean edge binding across high-volume bedding manufacturing lines.
