ABSTRACT:
An apparatus for securing a sheet of filter material about the circumference of a dye tube. The apparatus includes a mandrel support table having a tube loading station, a sheet wrapping station, a sealing station, and a discharge station; hollow, air permeable mandrels supported on the table; a table drive to sequentially index the mandrels to each of the stations; a vacuum chamber extending from the tube wrapping station to the sealing station to draw a vacuum inside each mandrel at and between the wrapping and sealing stations; a tube feeder for feeding tubes onto mandrels at the tube loading station; a sheet feeder for feeding sheets of filter material into engagement with tubes at the wrapping station; a mandrel drive for rotating each mandrel at the wrapping station to wrap the sheet around the circumference of a tube supported on the mandrel; and a sealer at the sealing station for sealing the sheet to itself to cover the tube.
