WILLIAM R. SEIGLE, OF ENASHUA, NEW HAMPSHIRE.
METHOD OF CONSTRUCTING WOUND PAPER TUBES.
1 040 438 Specification of Letters Patent. Patented Oct. 8, 1912.
Origihal application filed June 2, 1911, Serial No. 630,921. Divided and this application filed October 9,
v Serial No. 653,579.
To all whom it may concern: layers upon one of these mandrels and is Be it known that I, WILLIAM R. Serena, a citizen of the United States, and resident of Nashua, in the county of Hillsboro and State of New Hampshire, have invented new and useful Improvements in Methods of Constructing Wound Paper Tubes, of which the followin is a specification.
My invention consists in a method structing wound paper tubes.
The objects attained by the ractice of this method are the avoidance o distortion and crushing of wound paper tubes, and their production with rapidity and uniformity.
In the accompanying drawings, which show portions of a machine on which the steps in my new method are performed, -Figure 1 shows part of a machine in plan; and Fig. 2 shows a mandrel frame thereof'in section.
The machine illustrated forms the subject matter of applications for patent heretofore filed by me, Serial. Numbers 630,921, and 630,922, filed June 2, 1911. Such a machine forms a moist web of felted fiber couching from a cylinder rotating in the ulp vat, on to a carrier, and then couches t is moist web from the carrier to a mandrel which winds the thin moist web into a tube, which the rotation of the mandrel frame, the workman pulls out the pin E which slides in the housing c the pin E from the bore e in the end of the mandrel core E, enabling the mandrel to be swung out to the position shown in Fig. 2, when the mandrel proper, that is to say, the tube E with the paper tube wound upon it, may readily be slipped off the mandrel core E upon which a new bare mandrel tube E is placed; then the bare mandrel E and its core are swung back into place, the pin E being inserted and held in the bore eby means of the spring E By means of the above described device the paper tubes are moved from the machine and are "moreover held supported internally by the tubular mandrel E so that during the conveyance of conpaper tube firmly and tightly, maintaining The tube winding mandrels are shown in the drawings at E and are mounted in a mandrel frame which comprises a shaft E and heads E and E The mechanism of the tube winding machine comprises devices for intermittently rotating a mandrel frame so as to present fresh tube windingmandrelsto the paper web carrier B which delivers a web of paper the paper tube andthe outer surface of the metallic tube, so that the moisture in the paper tube must all escape outwardly. This insures a. drying of the tube from the outside inward and causes each successive'drying portion to shrink tightly upon those portionsof the tube which lie inside it, so that when the tube is completely dry it is entirely free from lamiuations, is compact, to be wound spirally under pressure on each straight and of true cylindricity. Then w hen mandrel when it is in proper osition. The the tubes are cooled the metallic interior mandrel itself, that is to say, the cylindrical support shrinks away from the inside of body on which a pa er tube is wound, con-v the paper tube and slips out very easily. sists of a tube E which is so proportioned At no stage in the operation of the tube as to slide over the mandrel'core E with a manufacture is the tube subjected to any fairly close sliding fit: The mandrel core but the gentlest handling. For this reason t is journaled at one end on one of the waste due to injury of the paper tube is blocks E mounted in the frame head E avoided and the quality of the output imand at the other end on one of the half bear proved. mgs E in which the mandrel core is held The materials of WhlCh tubular mandrels centered by a spring controlled sliding pin are composed should be such as to resist E. When a tube has been wound spirally, corrosion 1n the presence of moisture and in a number of superposed closely coherent such substances as may be included in the presented at the front of the machine by to the drying room and during the opera-' close contact between the Inner surface of quickly and easily re-,-

mandrel and drying the moist pulp tube from the outside inwardly. then allowing the mandrel to cooland contract away from the paper tube.
