6 Claims. (Cl. 118-60) This invention relates to an apparatus for selective pattern impregnation or coating.

No interchange of parts is required to convert the de vice from one type of patterned coating to another. The web to be coated passes over an impression roll desirably covered with felt or the like upon which a substantially uniform deposit of thermally liquefied coating material such as wax is maintained. Although the web comes into direct contact with the coating material on the felt, little transfer of the coating material to the web occurs except as the web is pressed against the coating-impregnated felt by a die roll which is heated. At the points of heat and pressure, transfer of the coating material into the web occurs. If the heated pressing roll is cylindrical, the coating will be uniform over the entire surface of the web or over such width of that surface as is engaged by the heated pressure roll. If the pressure roll has a periphery patterned with ribs or the like, the web will be coated in accordance with the pattern.

Changes in the type of coating desired are accomplished simply by shifting a carrier upon which two impression rolls are mounted, whereby the one or the other will engage the work to force it against the felt covered bed roll.

In the drawings:

Fig. 1 is a view in side elevation of a device embodying the invention.

Fig. 2 is a plan view of the device shownin Fig. 1, portions of the frame being omitted.

Fig. 3 is a view taken in section on the line 3--3 of Fig. 2.

Fig. 4 is a view taken in section on the line 4--4 of Fig. 3. v

Fig. 5 is a view on an enlarged scale taken in section on the line 5-5 of Fig. l. I

Fig. 6 is a fragmentary detail view in plan of the transfer roll and doctor plate in the coater tank, the tank being shown in section.

Fig. 7 is a fragmentary plan view of a portion of a patterned web exemplifying one type of coating which can be done.

Fig. 8 is a plan view showing a fragment of a web exemplifying a different type of coating.

A tank 10 is supported from frame 11 by means of bars 12 which are provided with slots 13 through which studs 14 connected with the tank project to guide the tank for adjustment. Nuts 15 threaded to the studs support the tank and may be tightened upon bars 12 to main tain the adjustment. The adjustment may conveniently be made by means of setscrews 16 shown in Figs. 1 and 3, these being threaded through ears 17 depending from barls; 12. The setscrews bear against the rim of the tan Assuming that the coating material is paraflin or other material which requires heat to maintain it in liquid form, the tank is provided with heating elements 18 in any desired number. Mounted on bearings 19 at opposite sides of the tank is a transfer roll 20 partially embedded in 2 the coating material and freely rotatable on bearings 19. A doctor plate 21 is mounted in the tank, its leg portions 22 being supported externally upon the bearings as best shown in Fig. 3 and Fig. 6.

The purpose of adjusting the tank bodily upon the supporting bars 12 is to adjust the pressure engagement of transfer roll 20 with the absorbent covering 24 of bed roll 25. The absorbent covering 24 is desirably felt but the invention is not limited to the use of this material. The shaft 26 which supports bed roll 25 is power driven by means of chain 27 (Fig. 4) and frictional engagement of its absorbent covering 24 with the transfer roll 20 rotates the transfer roll in the bath 28 of coating material in tank 10. The doctor plate 21 performs its conventional function of rendering uniform the depth of coating on the periphery of the transfer roll 20 and the degree of pressure between the transfer roll and the felt or other cover at 24 will determine the extent to which the covering is impregnated with the coating material. With higher pressure, a greater amount of the coating is squeezed from the felt.

The web 30 to be coated'passes over the absorbent surface of the bed roll 25. When paraffin or other similar material is used for coating purposes, a negligible and surprisingly small amount of coating is transferred to the web by mere contact with the absorbent covering 24. However, if the webis forced into contact with the impregnated covering 24 under heat and pressure, the parafiin or the like will enter the web. This makes it possible to impregnate the web in any desired pattern, according to the contour of the roll or rolls which supply the heat and pressure. The webs thus impregnated may comprise a wide variety of materials of which ordinary cotton fabric and ordinary paper or other cellulosic webs are representative.

The bearings 32 for the shaft 26 which carries the bed roll 25 are mounted in housings 33 supported on the rim of tank 10 as best shown in Fig. 4. The tops of these housings are provided with ways 34 in which slides 35 are retained by gibs 36. The slides support brackets 37 for a subframe 38 which supports the pressure rolls 40 and 41. The preferred arrangement is best shown in Fig. 5.

Sleeves 43 are held in the sub-frame 38 by setscrews 44 (Fig. 4). These sleeves support the inner races of bearings 45, 46 upon which the tubular extensions 47, 48 of the given impression roll 40 or 41 are mounted. These tubular extensions are bolted to the ends of the roll. In the case of extension 48, this is bolted to a driving gear 49 which receivesmotion from gear 50 and is, in turn, bolted to the end of the roll.

Sleeves 43 are, of course, non-rotatable. port within the respective impression roll one or more tubes 52 within which are disposed one or more heating elements 53 supplied with current by conductors 54 in conduits 55 which are connected with the ends of the stationary sleeves 43 all as shown in Fig. 5.

The gear 50 which communicates motion to the gear 49 is driven by a shaft 57 mounted at one side of the sub-frame 38 and supporting, externally of the sub-frame, a sprocket 58 driven by chain 59 from a sprocket 60 on shaft 26 as best shown in Figs. 1 and 4.

While the drive to pattern roll 40 has been specifically described, the drive to impression roll 41 is identical, as will clearly appear in Fig. 2.

By means of the adjusting screws 65, 66 threaded into the arms 67, 68 at the ends of the ways 34, the slides 35 and brackets 37 can be adjusted transversely as viewed in Figs. 1 and 3 between extreme positions defined by the adjustable stops 70. The purpose of the adjustment is to bring either of the impression rolls 40 or 41 selectively into pressure engagement with the web as the web They suppasses over the absorbent peripheral portion of the bed roll 25. As above indicated, the 'nature or pattern of the impregnation of the web Will depend upon the nature or pattern of the periphery of the pattern roll.

Thus the-impression roll is provided peripherally with staggered ribs 72 the pattern of which is shown most clearly in Figs. 2 and 4. When these heated ribs force the web 30 into contact with the impregnated felt coverin'g24 of bed 25', the web becomes impregnated in areas 73 having a pattern corresponding with that ofthe ribs 72 on the impression roll 40 (Fig. 7). It will be understood-that the pattern indicated is merely by way of exefr'iplification and any other-pattern of ribs or projectioris from the face of either impression roll would likewise produce a corresponding pattern of impregnation ofthe web. Solely in order to provide a clear differentiation in pattern'as between impression rolls 40 and 41, the latter has been shown with a smooth'cylindrical surface which, when in use, produces an over-all coating such as that indicatedat 74 in Fig. 8. It is not intended that the invention be limited to a choice between an overall coating and a pattern of staggered strips of impregnation. Rather, it is intended that the over-all coating be regarded as a pattern differing in any manner from that produced by roll 40. p

7 Changed from one form of coating to another requires only the disengagement of one roll from the work and the engagement of the other roll therewith in any desired manner, both-impression rolls coacting with the same bed roll. The means of adjustment shown has been found satisfactory but is only illustrative of one possibility in this regard.
