Appeal No. 98-1380
Application 08/786,741
DECISION ON APPEAL
This is an appeal from the final rejection of claims 1
to 16, all the claims in the application.
The subject matter in issue concerns a roll forming
machine which can be changed from making Z-shaped purlins to
making C-shaped purlins, and vice versa, by changing the vertical
position of the roll stands on one side of the machine relative
to the roll stands on the other side. Claim 11 appears to be the
broadest claim on appeal, and reads:
11. A roll former line for forming different shapes
comprising:
a bed;
a vertically-positioned linear bearing attached to the
bed;
at least one first roll stand attached to said bed for
vertical adjustable movement;
top, bottom, and middle spindles journaled to said
first roll stand in vertical alignment with each other;
top, bottom, and middle forming rolls disposed on said
top, bottom, and middle spindles, respectively, said top and
bottom forming rolls working against opposite sides of said
middle forming roll, said top and middle forming rolls acting as
a first alternative pair of forming rolls and said bottom and
middle forming rolls acting as a second alternative pair of
forming rolls;
