Hoping to tap into some real-world bindery experience here...
We've been running a Duplo DPB-500 for five years now, and we've had two long-standing issues that multiple service visits haven't resolved. We're trying to determine if this is a known mechanical characteristic of the machine.
Cover skew:
• Cover skew varies from run to run, anywhere from 0° to 0.25°
• The skew is small but measurable, and shows up over the length of the spine
• We've implemented a counter-skew in the design phase that centers most output, but it doesn't eliminate variance
Scoring mismatch:
• The spine score and the fold do not consistently coincide
• The score is typically off by 1/16", resulting in a less crisp fold
These behaviors have existed since it was first installed. I'm interested in hearing from anyone who has run, installed, or refurbished a DPB-500.
Thanks in advance! I appreciate any insight from anyone who has lived with this machine.
