    With our Differential Air Shaft, you are able to run multiple rolls on a single shaft while maintaining equal tension on all rolls. The internal differential slip allows for running rolls with a wide range of core sizes and types without using cones, core stops, or spacers. It also will not have any “wobble” or side to side movement. Our Differential Air Shaft is easy, safe, reliable and efficient to use.

    Features

    With easily controlled tensions from under 0.15 PLI, it is able to wind multiple cores down to ½” width. It can also have face lengths up to 100” in 70mm – 10” Diameter.

     

    The Differential Air Shaft also has patented GlideLock™ Clutched Rollers that auto-lock to equalize tension on multiple width cores that can be placed anywhere on the shaft.  It features a bi-directional, internal clutching mechanism which actuates based on the location of each core on the shaft. When the shaft begins to rotate, the rollers under each core lock independently and apply tension to each individual core. As the material is wound onto the cores, the GlideLock™ Clutched Rollers self-adjust to ensure the correct tension. And slide bearings on each GlideLock™ Clutched Roller allow cores to slide on and off the shaft quickly and easily. Heavy, finished rolls slide effortlessly off the shaft and decrease load time.

     

    Customization

    Our differential is custom designed to fit your specifications. When placing an order for the Differential Air Shaft, we ask that you specify whether you need a quote for the double journal, cantilevered or flanged version so that we can make sure your differential shaft fit your needs and specifications.

     

    As with all of our shafts, we guarantee that your Differential Air Shaft will be designed and manufactured to the same tolerances as all of our industry’s leading shafts.

     

    Availability

    These shafts are typically available 4-5 weeks after ordering. Please contact our office for a more specific lead time.

    The Convertech Leaf Air Shafts are recommended for use with thin walled cores and are well suited for thin wall or narrow cores. They can be used with thin-walled paper, steel, plastic, or fiber cores. Convertech’s Leaf Shafts are less expensive and lighter than our competitors’ leaf shafts.

     

    Features

    Our Leaf Shafts are available in core diameters ranging from 1” to 6” and face lengths up to 150”. The Leaf Air Shaft can be designed in four styles: Small Diameter, Narrow Web, Wide Web, and Heavy Duty.  Fixed leaves are available on all styles to assure uniform expansion.

     

    The advanced integration of high-quality materials guarantees our Leaf Shafts grip firmly and expand precisely. Anodized aluminum leaves expand uniformly along the entire length of the Leaf Shaft, assuring a firm grip.

     

    Customization

    Our Leaf Style Air Shafts are custom designed to fit your specifications. When requesting a quote for the Leaf Shaft, we ask that you specify whether you need the bored, double journal, cantilevered or flanged version so that we can make sure your leaf shaft fits your needs and specifications.

     

    As with all of our shafts, we guarantee that your Leaf Shafts will be designed and manufactured to the same tolerances as all of our industry’s leading shafts.

    Our Lateral Motion Shafts are perfect for on-the-fly adjustments. Lateral adjustments can be made while the machine is running. The Lateral Motion Shaft is an economical alternative to more expensive web guide systems. They are the perfect shafts for printing presses, inspection machines, laminating stations, portable unwinds, and collators that support light loads and utilize webs of 30” and under.

     

    Features

    The Lateral Motion Shafts are made with leaf or continuous lug expansion. They can be used for cantilever or flange mounted applications. These shafts are designed to make precision lateral adjustments with the adjustment knob. The adjustment knob moves the shaft in a 1” range of lateral movement to ensure alignment of rolls.

     

    The Lateral Motion Shaft can be designed with diameters from 70mm to 10” and face lengths up to 30”.
