Card Skew on the Line: How to Keep Cards Straight
Cards coming out crooked in the box — feed skew is the most overlooked fault on a card line. This post breaks down five causes and fixes so crooked cards never reach collation.
Last month a customer sent us a line video: every card in the box was tilted, like someone had just stuffed them in. His first thought was "the machine is broken," but skew is almost never a broken machine — it's the card drifting a little during transfer until collation can't save it. Feed skew is the most overlooked fault on a card line: no alarm, no jam, just a reject the moment the buyer opens the box. Here are the five most common causes our engineers see, and how to tune them out.
1. Guides Off-Center — Card Hugs One Side
2. Belt Speeds Don't Match
3. Picker Misaligned or Tilted
4. The Cards Themselves Are Warped
5. No Centering — Drift Over Distance
Why It Matters on a Card Line
Skew won't stop your line, but it quietly eats yield: uneven boxes, seals clipping the edge, a tilted card the moment the buyer opens the box. Solid feed alignment is the foundation of a correctly collated, straight-out-of-the-box set — and the reason a collector reorders. Simply put, the line can run fast, but if it runs crooked it runs for nothing.
