Operating Roll Loading with Your Material Roll Slitting Systems

Before loading a roll, first, you must displace the arm of the machine to a position away from any potential interference. Thermex-Thermatron recommends you leave the machine arm on the side opposite to the roll-dragging motor. A crucial part of the process: bear in mind the material winding direction, as this will determine the roll rotation direction to select.

To load the roll into the machine:

  1. Open the plate protector to prevent from actioning the machine with the key; and then proceed to close the claws using the special tool. While doing so, take care to not press the axis. 
  2. Activate the pneumatic switch to release the axis. 
  3. Open the claws of the plate with the special tool, ensuring that one of the claws remains placed in the lower part of the axis. 
  4. Displace the axis, pivoting it at the end opposite to the plate. 
  5. Load the roll in the axis, using the support of a mechanical device (such as a crane or a pallet jack). 
  6. Next, fit the axis at the center of the plate claws, closing the claws while avoiding pressing the axis. Use this step to guide the entry of the axis into the engine plate joint. 
    • Place the head in its working position (closed). 
    • To execute this, first set the pneumatic switch to the right. 
  7. If necessary, raise up the axis, accompanying it, so that you may fit it inside the plate set — and avoid blocking. 
  8. Once the roll is placed in its working position (directly in contact with the plate), remove the mechanical loading device. 
  9. Next, open the plate claws to fix the roll. While doing so, see to it that the roll is not loose, protecting the cardboard tube from deforming. When the anchorage of the roll is finished, the claw key must be withdrawn. Then, you can close the protector of the key. Ensuring that the claws press correctly against the cardboard, you can achieve the last turn with a torque wrench, utilizing a counter-clockwise direction. 
  10. Contingent upon the kind of cut, if required, fit the mobile plate to the other end of the roll. 
  11. The machine is now ready to be rearmed.

Keep in mind, the unload will be the inverse process to the load. Before unloading the roll, you must displace the arm of the machine — once again, away from any potential variables that could disrupt it. 

  1. Open the plate protector and use the special tool to close the claws, making sure to not press the machine’s axis. 
  2. Place the head in its load position (opened). To do so, set the pneumatic switch to the left. 
  3. Open the plate’s claws with the special key, so that one of the claws remains placed in the lower part of the machine’s axis. 
  4. Now you can displace the axis, pivoting it once again towards the end facing opposite to the plate. 
  5. Withdraw the trim or cut bands; and if the weight makes this step of the process necessary, you can do so using a lifting platform.

With some slitters, sticky material can cause abrasion or friction, where the slitting process could cause it to stick further as it heats up the material. Using the wrong tools can cause undue heat to the material. The Oteman slitting advantage: these machines do not require the material to be unwound. This means sticky material will not pose potential issues, because there is no undue heat added to the slitting process (a rapid-fire technique sometimes referred to as “saw it off the log”).
