Description

No. 859,383. PATENTED JULY 2, 1907.
v E. HAEFBLY. MACHINE} FORMANUFAGTUBING INSULATING TUBES.
APPLICATION FILED SEPT. 6. 1904.
contact as to produce a tube of great compactness and? density as well as of uniform dimensions. The length of the tube formed may be substantially equal to the length of the drum or of less length, ii desired, and a tube of any desired diameter may be made by selecting a drum of proper diameter upon which to form the tube.
The means for driving the drum, the'iorm oi the pressure device and the means for applying the heat may, of course, be varied from what is shown without departing from my invention. i
1 claim as my invention: 1. A machine for manufacturing insulating tubes comp ng a rotary drum to receive successive layers of sheet material, a pressure device located above said drum and having a pressure surface of inverted V-sliape that en- .gages said material along two lines of contact only, and
sive layers of fabric and binding material, a pressure de- -vice having a pressure surface of inverted V-shape that engagesthe outer layer of wound fabric along two'lines of contact, whereby ,the weight of the device imparts a constant pressure to said fabric and binding material, and means for heating the fabric and binding material as they are wound'upon the drum.
3. A machine for manufacturing insulating tubes comprising a drum, means for rotating the same, a pressure device supported solely by the material wound upon said drum and having a pressure surface of inverted if-shape,
means for guiding said pressure device and means for heating said pressure surface.
. 4. In a machinefor manufacturing insulating tubes, the combination with a drum adapted to receive successive layers of sheet fabric and means for rotating the same, of a pressure device located above the drum having a pressure surface of inverted V-shapc ihui rcsisd'rceiy upon the material wound thereon, and means for heating said pressure surface.
5. In a machine for nmnufncturing insulating" iubcs, the combination with :1 rotatable drum adapted to receive successive layers of sheet fabric and binding material, of a pressure device comprising two angulariy disposed pressure pintcs that rest freely and equally upon the upper side of the drum or the material wound thereon and means for raising said pressure device out of contact with the drum comprising a lost motion spring connection device.
6. In a machine for nmnufncturim: tubular insulating bodies from sheet material, the combination with n rotutable drum, :1 pressure device comprising two diverging hollow plates and resting ircciy upon ihc material wound upon the drum and means for heating said plates.
7. In ii machine for manufacturing tubes from sheet fabric and binding material, the combination with :1 rotutable drum, of a pressure device above the drum having a pressure surface of inverted Vshnpe and the weight of which is entirely supported by the material wound on the drum, means for heating said pressure surface. and rnising and lowering means for said pressure device that cinbodies a lost motion spring connection.
8. in a machine for nuinufnctnriug insulating tubes from sheei fabric and binding material, the combination with a frame. a shaft journuled therein, and a drum dctachabiy mounted upon the shaft, of a pressure device supported by the material wound upon the drum and huvin: a pressure surface of inverted V slinpe, and menus for heating said pressure surface. l
In testimony whereof l have signed my numb to this 7 specification in the presence of two subscribing witnesses.
