1. A method for manufacturing a glass ribbon comprising:
moving the glass ribbon along a travel path in a travel direction;
directing a first ribbon portion of the glass ribbon to a winding apparatus to wind the first ribbon portion into a roll;
detaching the first ribbon portion from a second ribbon portion of the glass ribbon;
separating the second ribbon portion into a plurality of separated ribbon portions;
directing a first set of the plurality of separated ribbon portions toward a disposal apparatus to crush the first set of the plurality of separated ribbon portions;
forming a stack with a second set of the plurality of separated ribbon portions;
moving a conveyor between a first position outside the travel path of the glass ribbon and a second position intersecting the travel path,
wherein the first ribbon portion is directed to the winding apparatus when the conveyor is in the first position, wherein a segment of the first ribbon portion upstream from the winding apparatus is unsupported and spaced a distance from the disposal apparatus when the conveyor is in the first position;
measuring a distance between the segment of the first ribbon portion and a location within a clean room environment within which the first ribbon portion is located; and
adjusting a rotational speed of the winding apparatus when the distance is outside of a predetermined range.
