ABSTRACT:
An apparatus of the type including a guide for guiding longitudinally advancing tubular textile goods, and a member disposed within the advancing tubular textile goods for flattening a portion of the advancing tubular textile goods into a flattened portion having a pair of major opposed sides which jointly comprise the entire surface area of the flattened portion of the tubular textile goods. The guide is comprised of a pair of opposed rollers defining therebetween an elongated narrow slot or nip for receiving the advancing tubular textile goods in the flattened configuration. The member for flattening the advancing tubular textile goods comprises a plate-like member which is disposed in use within the tubular textile goods above the pair of opposed rollers. A method of inspecting tubular textile goods comprises advancing the tubular textile goods over a plate-like member so that they are stretched flat as they pass over the plate-like member, passing the flattened tubular textile goods through a narrow slot which is dimensioned to pass the same but which is too narrow to pass the plate-like member, and simultaneously inspecting both sides of the flattened portion of the advancing tubular textile goods in order to inspect the entire surface area thereof.
