Splice On-The-Fly Unwind Stand

PDC unwind stand which in addition to having two reels, splicing table, low material and material out sensors, also has a festoon unwind system that provides a buffer of sleeving material to allow the machine to continue to operate at half speed during the splicing process (40-50 seconds). The festoon material is driven by a separate drive. The operator mounts the new roll of material on the empty reel and gets a Low Material signal before the first roll runs out. When the first roll ends, the machine goes into the splice mode. If necessary the machine is cut to half speed while the operator splices to the new roll of material. Accumulation system includes the festoon, material clamp, and all required sensors and logic.
Benefit: allows roll changes while the machine is running, reducing downtime and increasing productivity.
