Modern AC frequency drives actually generate “noise” – electrical harmonics and transients that can affect other electrical components. Maxson uses proven grounding methods to minimize noise associated with drives. Among the standard designs employed by Maxson in their dual motor drive retrofits: Inclusion of an isolation transformer between the main line and the electrical cabinet […]

Unlike my older equipment, my new sheeter has a dual motor drive system governing sheet length and a programmable logic controller that manages machine functions. When the sheeter shuts down, how can I troubleshoot the cause?
Actually it is a lot easier to troubleshoot a machine that is controlled with electronics. Most new sheeters have a programmable logic controller (PLC) governing the operations of the sheeter instead of relay logic. Typically a dual motor drive with two motors, two AC drive and a motion controller takes the place of the mechanical […]
How can I increase the productivity of my sheeter? There seems to be a lot of time when the sheeter is not running because the operators are getting and loading rolls, removing skids, and doing paperwork.
It starts with scheduling. Orders should be set up ahead of time so the rolls and skids are available for the job. Next, stage the rolls behind the sheeter so the operators are not waiting for them. An adequate number of skids should also be placed near the stacker so they are readily available to […]
What skill level should a sheeter operator possess?
An operator must be thoroughly familiar with how the machine works. Mechanical aptitude is helpful in learning this. The operator must also know the safety requirements for the machine. Training in the setup procedures is necessary. Experience in web handling is helpful.
How long should it take to make a full size change from single pile to two pile service on a sheeter?
Let’s look at setting sheet length first. Setting up for length changes on a modern sheeter can be done fairly quickly. There are four items to be set. One is the overlap carriage located in the delivery system. This is typically a hand wheel adjustment with a scale indicating the sheet length. The next item […]
When sheeting light weight paper grades, the sheets have a tendency to jam at the stacker. Even though we direct air at the back of the pile, the problem still persists. Are there other ways to overcome this problem?
Generally, jam ups at the pile are caused by sheet packets lacking sufficient rigidity that they buckle as they drop or are pushed out into the pile. There are a number of set up issues to consider depending on the type of jam up. Insufficient momentum to drive the sheets forward When there is not […]
On startup, when running two rolls of paper, I have difficulty with sheet hang backs in the first 6″ (150 mm) of the pile. I am not using a custom pallet. I am using standard skids. How can I overcome this situation?
If the hang backs are only in the first 6″ (150 mm) of the pile, my first conclusion might be that the material will not deliver with such a substantial drop off from the delivery section to the skid. Try to get whatever additional height can be gained by raising the side jog blades to […]
When I slit a web into two streams across, the cut sheets tend to interweave in the overlap section, As a result, the front edge of the sheets are damaged by the center jogger blade. What can I do to prevent this?
Make sure there is adequate belt tension in the bottom slow speed tape section, so that the weight of the sheets does not cause any excess drooping. Adding an edge turner between the two streams in the slow speed tape section prior to the stacker will also help to split the two piles. A final […]
I have an automatic pile lowering feature on my stacker. When the pile lowers, the sheets skew, causing an unevenly jogged stack. How can I improve pile quality?
Your problem could be caused by the following: One of the jogger blades is lower than the other. Set all jog blades to the same depth. The load table’s guides are loose or worn. If the table sways when rocked, inspect the guides and address accordingly. The front to back jog box may be misaligned. Make […]
When sheeting light weight board, the sheets have a tendency to turn under at the edges entering the stacker. What can I do?
Try to give the sheet some added rigidity by using edge turners and crimpers. Edge turners (or “shoes”) flare the edges of the sheet in the delivery system. Crimpers are placed in the center of the web path to corrugate the sheet, giving it added stiffness. When using edge turners and crimpers be careful about […]
