Patented Apr. 8, 1919.
Application filed :April 25, 1918. Serial No. 230,770.
To all whom-it may concern: Be it known that I, THOMAS SMITH, a o1t1- zen of the United States, residing at Cornell,
in the county of Chippewa and State of.
Wisconsin, have invented certain new and useful Improvements in Methods of Pasting and "Machines Therefor; and I do declare the following to be a full, clear, and exact description of the invention, .such as will enable .others skilled in the art to which itappertains to make and use the same.
My invention relates to Improvements in methods and machines of the character employed for pasting a plurality of sheets of paper or the like together to form a multiple ply board used principally .as a plaster substitute. In this form of machine, it has been found that a great waste of silicate orother paste used has-taken place and it is to prevent such waste that I have devised the present invention.
' machine embodying my invention Fig. 2 is a diagram showing more particularly .the manner in which the doctor or scraper bar separates the filler sheets and at surplus paste therefrom; Fig. 3wis a front elevation of the machine with parts removed; and Fig. 4 is a perspective view of the doctor or scraper bar and its carrying arms.
In the drawings above briefly described,
- the numeral 1 designates a well known form of pasting machine embodying a pan 2 forthe silicate or other paste; a roller 3 for guiding the lowermost of the two filler sheets 4 through said pan, a pair of Super-' imposed rolls 5 for pressing the two sheets 4 together and equally distributing the sili cate or the like thereover, and a pair of pressing rollers 6 which finally pressthe filler sheets and the two liner sheets 7 toether, paste being applied to the upper surface of the uppermost filler sheet by a suitable nozzle 8. In this form of machine, an
part of this spec ifi additional roller is usually employed above the rollers 5 for guiding the upper liner sheet 7, the supporting means 'for't-his roller rislng from the bearings 9 of the upper roller 5. Due'to the nature of the present invention however this additional roller is omitted and the horizontal ends 10 of a pair ofinclined arms 11 are bolted to the bearings 9 as seen at 12.
he lower endsof the arms 11 are turned substantially upon themselves to form a pair of U-shaped sockets 13 of rectangular contour, the ends of saidsockets snugly yet removably receiving therein the ends of a polysided doctor or scraper bar 14. This bar is located between the rollers 5 and 6 and serves to separate the two filler sheets 4 after passage thereof between said rollers 5, and while said sheets are thus separated,
the bar 14' scrapes all surplus paste or the like therefrom. The several sheets then pass between the rollers 6 and are securely pressed together by the latter to form the 1 multiple. ply board indicated at 15., Bolts 16 pass across'the open sides of the sockets 13 to retain the bar 14 in place but by removing th'esejbolts, the bar may be turned to present new scraping edges to the filler sheets, said bar being so located that two of its edges Wlll engage said sheets while a third edge will be disposed toward the rolls- 5. to assist in separating the two sheets.
- By passing the filler sheets 4 between the rollers'5 after application of paste, and then separating said sheets to remove the surplus paste therefrom, much better results are obtainedthan when an attempt is made to remove the excess paste before passage of the sheets between the rolls. This is due to the fact that by pasting the two sheets together and then separating them, the surplus paste will project from the inner surfaces of the sheets in a multiplicity of globules, and itis these globules that are scraped off by the bar 14. Bars of this general character are commonly known to the ,art as doctors The lower liner'sheet pre l litolpractioally any of the well known ,types of pasting machines by removing the come coated with such paste, said sheet then passing between the rollers 5 with the upper filler sheet 4: and thus appliy'ng the paste to the latter. At the same time, paste is applied to the central portion of .the upper sheet 4, along its upper side, by the nozzle 8, and as the'sheets pass between the rollers 5, this paste is spreadevenly'. and at the same time the u per roll 5"applies the paste to the lower sur ace of the up er liner sheet 7.
fer'ably' passes under the pan 2 as shown and is supplied with paste at the rolls 6 from the lower surface of the'lower filler sheet 4.. As the two filler sheets leave the rolls 5, they are spread aste is,-r,emoved:.from their inner faces. hese sheets thentravel to the rolls 6' how ever and are pressed-firmly together by the latter, the liner sheets 7- being at the same time applied to the outer faces of said filler sheets,,whereby to form the complete. board 15,
From theforegoing, taken in connection with the. accompanying drawings, it will be obvious that. although my invention is of comparatively simple and inexpensive na- 'ture, i1; willfbe highly efficient for the 'purpose intended; .Since probably the best results are obtained from the arrangement shown and described, such arrangement is preferably employed, but within the-scope of the. inventionasaelaimed, considerable lati-.-
-tude is allowed forlapplication' of the inven-.
tion to difi'erent forms of machines. It is:
also to beiunders'tood that although I have used the termpaste in the foregoing and .in the' appended claims, this term is to be given a sufficiently broad interpretation to cover any of the well known viscous or glutinous fluids common] used in the manufacture of multiple ply oard.
I claim:
1 Q A machinefor untiting sheets of ma- 'terlal to form a multiple ply board, comprising a pair of rolls between which the sheets pass, means for applying paste' to and removing surplus paste therefrom after passage of said sheets between said rolls, and
' the surplus paste.
said sheets before passage-thereof between .sald rolls, means for separating said sheets 2. A machine for uniting sheets of material to form a multiple ply board, compris ing a pair of rolls between which the sheets forcing said sheets tightly together after removal of the surplus paste, saidscraper bar'havmg two of its corners disposed for contact with the separated sheets and a third corner disposed toward said first named pair of rolls to assist in separating said sheets. apart by the f doctor 14::and the surplus 3. A structure as specified in claim 2, to gether with a pair ofrigid arms for support ing said scraper bar, one endof said arms being anchored and. the other ends, thereof being turned substantially. upon themselves to form U shapedsocketsreceiving the ends of said scraper bar, and bolts passing across the open sides of said sockets to retain said THOMAS SMITH.
