ABSTRACT:
A method for fabricating doors having spaced sheets of flexible material with cross-memebers interposed and attached between the material. Flexible material is fed intermittently from material supplies to form both sides of the door. Between each feed step the material is connected to a cross-member in a predetermined operative position, in which the cross-member abuts a movable carrier. The positioning of the cross-member in the operative position is effected by the carrier which causes vertical material feed. The feeding of flexible material and connection of each cross-member is continued until the desired door size is accomplished.
