or pivot shaft 40. Shaft 40 pivotally supports by an offset hinge arrangement-4L- see Fig. 1-a pair of combination covers and arms 42. These arms rotatably support shafts 43 and each of said shafts mounts a pressing and feeding roll 44 knurled as at 45. These rolls are positioned-in spaced and parallel relation and the spacing therebetween may be varied, although in so varying the same, the rolls are varied 'rlative to the spacing between them and the applying roll 20. The two rolls 44 rotate in the same.

direction. 7

An arm 46 is socketed asat 47 and a clamp 48 detachably mounts a bracket 49 supporting an aligning guard .and guide 50. The bars 51 of the bracket 49'are slidable in'the openings 47 and are locked thereinrby the clamp screw 48 to position the guard and guide 50, so that the .predetermined width of adhesive is applied to the strip in its passage between the. applying roll and the two pressing and feeding rolls. v i

The feeding and pressing rolls are-yieldingly mounted and normally constrained toward contact with the applying'roll and by means of springs 52. The same, however, are preventedfrom such contact by adjust.- able stops 53. The feeding rolls, therefore, are free from adhesive.

The power for driving the pressing and feeding rolls is derivedfrom the applying roll so that the same are operable in timed relation. The shaft 13 mounts a pulley 54 which lies in the same plane as pulleys55 carried by the shafts 43. The housing is provided with elongated slots 56, through which the shafts extend and into the housing 11. The housing enclosed ends mount the pulleys 55. Each of said pulleys has more than 180 degrees of contact with the belt. The endless belt 57 runs uponan idler pulley 58, pivotally supported on arm 59 pivoted at 60. Associated with the shaft 60 is an arm 61 and a coil spring 62 is connected to the free end thereof as at 63 and anchored to the housingas at 64. The spring 62 nor1nally tends to'rock the arm 61 counterclockwisesee Fig. 3for loweringthe tensioning pulley 58.'f01 obtaining the desired driving tension in the belt.- The motor 15, therefore, not only rotates shaft 13 for rotating the applying roll, which in turn by frictional contact rotates the transfer roll, but also through the pulley 54 frictionally drives the feeding and pressing rolls 44. Y a

The invention claimed is:- 1. A gluing machine including an adhesive applyingroll arranged to support an end and edgewise presented sheet of material while passing thereover and adhesive is applied to the underface thereof, a pair of spaced sheet engaging and sheet conveying pressing rolls positioned lthereover, and each rolls and supporting the outer ends thereof and means supporting the opposite ends of said rolls and said supports; 3 r 1 2. A*device -of the-character described, comprising a base, a housing extending u wardlythereof and intermediate the en s,

a stationary overhanging arm extending therefrom, a pair of feeding rolls rotatably mounted, means associated with the arm and housing and pivotally supporting the rolls and permitting roll movement toward and away fromeach other, an applying roll therebeneath and in juxtaposition thereto, a standard for one end of the applying roll, said standard and arm supporting said rolls .to permit end and edgewise'presentationof a sheet, an adhesive container. positioned therebeneath, a transfer roll mounted therein and normally constrained towardapplying roll engagementand rotatable thereby, an electric motor mounted on the base opposite from the-container, and balancing said overhanging arm, and power meansoperable by the motor for rotating the applying roll and rotating the feeding rolls. 7

3.- In a marginal adhesive applying ma chine, the combination of a; base, a housing extending upwardly thereof, an overhanging arm supported by the housing parallel to thebase, a power shaft-supported at one end. by the housing, a standard terminating below thelevel of the arm and supporting the other end of the shaft, anap- I.

plying roll supported-by .the power shaft,

a pair of parallel and spaced, feeding rolls supported by the housing and arm, means normally-constraining said rolls toward each other and toward the applying roll, means pivotally supporting said feeding rolls upon 7 an axis lying in a plane intermediate said rolls and including the axis of the applying roll, adjustable stop means limiting the pivotal movementof said feeding rollstoward each other and-preventing applying roll contact, a pulley coaxial with each of said rolls,a'n endlessbelt operatively'associated withnot-less than 180 degrees of contact with each of said pulleys, and meansnormally tensioning said belt.

4. In. a marginal adhesive applying device of the character described, the combinafixed relationtothe arm, said container having an openingin its upper portion through which the applying roll projects, and a transfer roll yieldingly mounted in said container and normally constrained into applying roll engagement.

5. In a marginal adhesive applying device of the character described, the combination of an overhanging arm, pressure applying means supported thereby, a container detacha-bly mounted beneath the arm and means including a hinged cover for access, an applying roll rotatably supported in fixed relation to the arm, said container having an opening in its upper portion through which the applying roll projects, a transfer roll yieldingly mounted in said container and normally constrained into applying roll engagement, and means operatively associated with said transfer roll and arranged for overlapping the applying roll for scraping the same at the sides thereof and aligning the transfer roll therewith.

In witness whereof, I have hereunto afiixed my signature.
