Belt-form body conveyor

A belt-form body conveyor that conveys a belt-form body comprising:

• a plurality of non-contact guide portions over which portions of the belt-form body are wound, and that support the belt-form body in a non-contact manner;
• a drive unit that moves at least one non-contact guide portion out of the plurality of non-contact guide portions;
• and
• a control unit that causes the non-contact guide portion to be moved by the drive unit such that a length of a path in which a first edge in a width direction of the belt-form body travels is different from a length of a path in which a second edge which is opposite to the first edge in the width direction of the belt-form body travels,
• wherein the plurality of non-contact guide portions include;
• an upstream-side turn bar that, of the plurality of non-contact guide portions, is disposed furthest on an upstream side in a travel direction of the belt-from body, and alters the travel direction of the belt-from body;
• a downstream-side turn bar that, of the plurality of non-contact guide portions, is disposed furthest on a downstream side in the travel direction of the belt-from body, and causes a position of the belt-from body in a thickness direction of the belt-from body to match a position of the belt-from body in the thickness direction before the belt-from body is supplied to the upstream-side turn bar;
• and
• an inverter turn bar that reverses the travel direction of the belt-from body, which has been altered by the upstream-side turn bar, towards the downstream-side turn bar, and
• wherein the upstream-side turn bar and downstream-side turn bar are rotated in opposite directions when viewed in a direction aligned with a line that is perpendicular to a surface of the belt-from body before the belt-form body is supplied to the plurality of non-contact guide portions.
