Let-Offs
Powered Let-Offs are designed to unwind profile from coiled reels. They are typically utilized on crosshead extrusion lines and can be used for letting off metal reinforcement (e.g. automotive seal lines) or extruded tubes with or without reinforcement (e.g. hose lines). Let-offs are often supplied in conjunction with accumulators to ensure continuous supply of material to the extrusion line. Let-offs can also be used for transfer of bulk coiled extrudate to smaller consumer sized packages. Let-offs are typically dancer controlled to adjust reel speed as effective reel diameter changes and can be designed as single station or dual station. Machines are designed for a variety of different reels sizes and weights and can lift the reel from the loading position or couple to roll around reels.
