Abstract
The invention resides in winder for automatically winding sections of sheet material to form separate tubes. The winder comprises a base, a supply of sheet material and a material drive means on the base for advancing sheet material from the supply towards a station on the base located remotely thereof. A winding means is located at the station for winding a section of the sheet material about itself and about a rotational axis such that the involved section of sheet material is substantially wound in a tubular condition. A cutting means is provided and is located between the drive means and the second rotational axis for cutting the sheet material transversely of its length at points therealong corresponding to the end one section and the beginning of the next successive section to be advanced to the station. The winder further employs fastening means for applying a means to the tube created on the winding means to hold the sheet material in tubular form after the involved tube is released from its holding engagement with the winding means.
