There are now 3 kinds of coreholders available for Web Techniques WT-30 & WT-35 Series rewind systems.
- Lift-Off Air Coreholders
- Lift-Off Cam-Lock Coreholders
- Flange Mounted Air Coreholders
Lift-Off Air Coreholders
These coreholders offer the BEST OF BOTH styles (Cam-Lock and Flange Mounted Air). They can be removed and installed in a second or two with no tools. Inflation is by means of a rubber tipped air nozzle. The fill valve has a cone shaped hole so accurate nozzle placement is not required. Deflation is accomplished nearly instantly and comfortably by pushing down on the fill valve with a fingertip. A major advantage of this system is that Lift-Off Air Coreholders are 100% interchangeable with Lift-Off Cam-Lock coreholders. You can use air inflated coreholders for your most common jobs and save money by using economical cam-lock coreholders for odd jobs that do not require slitting. You can also graduate up from a machine with Lift-Off Cam-Lock coreholders to Lift-Off Air Coreholders with no modification required to the machine. Air coreholders can accommodate cores with a broader range of inside diameter tolerance. They expand concentrically for smoother operation, grip firmer, and release easier. An air coreholder is required in the rewind position if the machine is going to be used for slitting.
Lift-Off Cam-Lock Coreholders
This is the most economical coreholder style and is the type supplied as “standard” equipment. The advantage of Lift-Off type coreholders is that they can be installed and removed from a roll of labels while the roll remains on the machine surface. Heavy rolls can then be loaded or unloaded by sliding them on the table surface. Notes: Cam-Lock style coreholders cannot be used on the rewind spindle if slitting is going to be performed since it can only drive one core. Also, Cam-Lock coreholders cannot be used on metal or poly cores as the machined cam cannot “bite” into the core to secure it in place.
Flange Mounted Air Coreholders
Air coreholders can accommodate cores with a broader range of inside diameter tolerance. They expand concentrically for smoother operation, grip firmer, and release easier. An air coreholder is required in the rewind position if the machine is going to be used for slitting. Flange mounted air coreholders (picture below) are bolted to the machine spindles with fasteners which require time and tools to remove and install. Rolls must be installed and removed by lifting them over the coreholders. They grip and release by simply flipping a toggle switch. Compressed air is piped to the coreholder through a sealed passageway in the spindles (hence the need for permanent mounting). Flange mounted air coreholders are compatible with the optional foot treadle valve for hands free operation.

Common System Coreholder Diameters Available:
Two Types of Inflation Systems Available
The standard inflation system consists of an air filter/regulator, hose, and nozzle which are attached to the machine as shown. For even faster and easier inflation, our new Easy Reach Inflation system positions the nozzle out of the way above the table top. The nozzle is suspended on a tool retractor which allows it to be lowered for inflation and returns the nozzle to a parked position when it is released.
