On a flowline / ZX with separate winSaw program on saw side, the software works by continually increasing the Bar Queue with every bar cut. An issue has been found that if the operator rarely resets the program, it can build up in size and get “bloated” to the point where it does not perform correctly with the following symptoms:
• Missing / delayed labels
• Slow updates / performance
• Long time to start cutting a bar after loading
• Reprinting label delays +
On F027 O’Grady, the R axis position was identified to be creeping in a positive direction on each move. Because the R axis is open-loop (ie no encoder feedback to the e100 controller), there is no way of detecting or correcting this. The control system was fully tested on a separate setup and it has been confirmed that there are no issues with the software or wiring design. The root cause is not obvious. +
The infeed belts on Flowlines and Ecolines require the disassembly of the infeed tables to replace the belts.
Jointed belts will now be supplied when replacement required. These belts are cut and use threaded pins to join the ends into a continuous belt. +
This document records the result of the process carried out today to “normalise” the design and part notation for the PCBs that Stuga outsource. This follows confusion of poor naming and a lack of part numbers. +
These instructions allow the computer to be set up correctly ready for delivery to customer’s site. The customer can plug it in to a network connection and we can then connect to update backups, etc. +
There have been instances where the cylinder rod on a spindle has sheared, dropping the spindle down into the path of the gripper. Because the cylinder is still sensed in the home position the machine head will continue to operate causing damage to the gripper. +

As the development of uPVC systems has advanced, there is greater and greater use of pre-reinforced profile on Stuga machinery. The profile is often made of a recycled plastic and is inserted into full lengths of profile. It is fixed using a series of staples along the length.
The machines were not originally designed with this in mind. We have experienced four serious issues from testing this system in the field. +
