first sheet and the ap lication of the material I I This invention relates to the application of coating materials to sheets or the like and is concerned more specifically with apparatus by which a coating material, such as one which is fluent only when heated, may be applied to a sheet to rovide a film of the desired thickness. T apparatus is particularly useful in 'connectionwith afiixing one sheet to another by an adhesive coating, and an'embodiment of the invention suitable for that purpose will presently be described.
The apparatus of the invention includes a heated vessel for the coating material and means such as a roller forapplying a film of u the coating material to the surface of a sheet.
The roller is mounted so that its surface di s beneath the level of the coating material 1n the tank, and the sheet is led in contact with the roller to receive coating material therefrom. The thickness of the film so applied may be regulated b a doctor blade, prefera ly controlling t e amount of material picked up by the roller, and so mounted that it is maintained substantially at the temperature of the material in the vessel so that the coating material will not adhere thereto. The
a coated sheet leavingflthe roller is'next. en-
film from the gaged by a doctor ade having an interrupted workin edge which scrapes all the eet exce along spaced lines corresponding to the mterru tions. This doctor blade is also maintains substantially at the temperature of the material in the ves-j sel and for this purpose may be mounted to j; dip below the surface ofthe material in the vessel. The blade is preferably of thin sheet metal of good heat conducting properties, such as copper. t
The sheet with the spaced lines of coating material is next assed through driven pressing rolls with t e sheet to be united to'the I coated sheet also passing through the rolls and in contact with the coated face of the first sheet. The pressure applied to the rolls forces the sheets into firm contact and spreads the coating material in the spaced lines to cover the entire contacting areas of the sheets.
The spacing of the notches in the doctor blade and the depth of the notches determines so how much coating material is applicdto the can be closel contro edvso that a good cohe- -sion of the s sets is obtained without the use of an excess of the adhesive coating material.
.For' a better understanding of the invenaccompany;-
tion reference may be had to the ini drawing, in which ig. 1 is a viewof tudinal section;
Fig. 2 is a fragmentary face view of a novel dogtor blade forming part of the invention; an
theapparatusin longi Fig. 3 is a fragmentary plan view of a piece of material being coated at one stagein the operation.
- The apparatus comprises a tankor vfel 10 which contains a sup ly .11 of the coa ing material and is heated y a burner 12 when the coating material usedis one which is,
surface. The thickness of the layer of, material adhering to the roller is controlled in' any convenient manner, for example, b a doctor blade 15 mounted so that its vedge' es close to the surface of the roller and thuspermits onl a selected amount of the coating materi to adhere to the roller.
The sheet 16 of materialto be coated is led over the surface of the roller 14 in contact therewith and picks ,up from the roller a film of coating material over the entire surface which contacts with the roller. Be end the I.
roller, the sheet' passes over the ge of. a doctor blade 17 This blade is formed with spaced notches 18 in its operating edge. As the coated surface of the sheet passes over the edge of the blade the latter removes all of the film from the s eet except along lines 19. which extend. in the direction of movement of the sheet. The spacing of these lines of coating depends onthe spacing of the notches and the width and depth of the notches determines the amount of coating material in each line.
The blades and 17 are preferably of thin sheet metal of good heat conductivity, for
example, of sheet coplpler thick, and when I a coatin become uent is used in the apparatus, these material w ch requires heating to blades are mounted in such manner as to be maintained at the same temperature as the coating material. This may be accomplished by mounting the blade so that it has a portion continuously lying within .the mass of coat-,
ing material or, if the tank is of metal, the
blade may be mounted directly on the tank high. When the blades are mounted so that their temperature is substantially that. of the coating material, the material which is" scraped off the roller or the surface of the sheeti as the case ma be, does not adhere to v the b ades but flows own them and back into the tank. v
. The sheet with the spaced lines of coating on it passes from the doctor blade 17 to a pair of driven pressure. rolls 21. The sheet 22 to be aflixed to sheet 16 is also led to the rollsand' both sheets ass through the rolls together, sheet 22 eing forced into contact with that face of sheet 16 on which the lines of coating material have been formed. The
' pressure exerted by the rolls causes the lines of coating to flatten and spread and, by proper regulation of the amount of coating applied and of the spacing of the lines by the use of a doctor blade-of the desired edge configuration, just suflicient coating may be applied to give a strong bond between the sheets without excess coating which would weaken the joint.
The apparatus of the invention is articularly useful in producing a metal-ole roofing consisting of a felt base-and a metal layer thereon. In making such material, the metal band employed is treated in'the manner of sheet 16, the felt base being united thereto in the rolls 21. However, if desired, the felt may receive the coating, though it is prefer able to. apply it to the metal since the latter is usually narrower than the felt and the application of the coating to the metal thus prevents the coating from reaching parts of the felt not in contact with the metal.
