A reel spool is a large diameter mandrel used for winding and possibly storing large rolls of paper board and tissue. More and more mills are winding on cores (10", 12" 14", 16" on up) right on the tissue & paper board paper machines.
Why? They do this to by-pass the paper machine winder. By winding on cores directly at the paper machine and sending the jumbo rolls of tissue, towel or paper board directly to converting or out the door to customers, they eliminate an entire operation. Tissue machine re-winders cost a great deal of money. Not only do you have to maintain them, but you also have to staff them.
In today's mill market, every nickel counts. Goldenrod manufacturers the industry standard when it comes to pneumatic, multi-bladder reel spools.
When considering an expanding reel spool, there are three options.
1. Mechanical Design
Cores are slid onto the non-air reel spool until they hit a core stop at the far end. Then the operators place a large "nut" on the near side and tighten with a "spanner" wrench until all cores are secure.
Disadvantage: Safety (reports of lost fingers due to misuse of wrench and back injuries due to cores being too difficult to dislodge are common);
Time: Iit takes more time to core up and de-core the rolls; this design has no centering which may limit speed; Difficult to change web widths.
2. Axial-Pneumatic Core Clamps
Pneumatic clamps are placed on either end of the reel spool acting as book ends for the empty cores. They clamp down to the reel spool using air.
Disadvantage: This design still takes too long; difficult to change slit widths; no true centering which may limit speed.
3. Pneumatic Reel Spools
This option is the choice for most new operations or for those seeking to upgrade to the most efficient method of production.
Advantages: Easy changeover; enables maximum machine speed (w/our centering design); simple maintenance (with our design); fast payback.
