Transair Air System

Needle Grippers

Needle grippers are special grippers actuated by compressed air. The needles are pressed into the workpiece by the compressed air and are retracted either by a spring or by compressed air. The needles are extended at an angle to ensure reliable gripping of the workpieces.

Application areas

  • Pneumatic needle gripper in compact, maintenance-friendly design with manual, continuously adjustable stroke for handling materials that are difficult to grip using vacuum such as composite textiles, etc.

    Advantages of Needle Grippers

  • Safe handling of soft or unstable materials.
  • Various types available for individual operating conditions.
  • Various needle diameters available; stroke can be adjusted.
  • Typical Applications

  • Handling of porous and/or unstable workpieces such as textiles, insulating materials, foam materials, felt and fleece, carpets, filters, woven materials (such as carbon fibre), polystyrene and metal foam.
  • Construction

  • Driven by double-acting pneumatic cylinders.
  • High-strength housing with lightweight design (1).
  • 3 sizes with needle strokes of max. 3 mm, 10 mm or 20 mm.
  • Adjustment wheel (2) with scale for continuous, simultaneous stroke adjustment.
  • 10 needles (3) with diameters of 0.8 mm or 1.2 mm (depending on the model).
  • Insertion angle of 30° or 45° (depending on the model).
  • Optional sensors for monitoring the needle end positions.
  • Can also be mounted with the Schmalz holder system HTS.
  • Your Advantages

  • Safe handling, even of small and very unstable workpieces.
  • High acceleration for minimised cycle times.
  • Individual adaptation to different workpiece geometries.
  • Fast start of operations and set-up time.
  • Synchronous extension and retraction of the needles; reduces the need for couplings and hoses.
  • High level of process reliability and exact positioning; short cycle times.
  • Low maintenance.
  • Highlights

  • Intersecting needles and small gripping area.
  • Low weight and double-acting pneumatic cylinders.
  • Tool-free simultaneous needle stroke adjustment up to a maximum of 20 mm.
  • One central pneumatic drive.
  • Blow off function for fast and reliable load release.
  • Quick and tool-free cleaning of the needles and replacing the needle modules.
