In a machine for making envelopes and the T and 3 is slightly p d in plan and also is so like from a web of material, the combination of 5 set that t forward e is slightly lower t means for continuously advancing the web, and the t ilin d to p i of p n up or notching devices at each side of the advancing sl w down of the Web speed to y the 8 web adjacent the edges thereof for notching V p and yet insuring that the notches II will the web at predetermined intervals, each of said be clean cut. notching devices continuously rotating about axes parallel to the direction of travel of the web and having their leading edges slightly lower than their trailing edges.

2. In a machine for making envelopes and the like, the combination of a segmental disc for applying aligned stripes of adhesive to one face of a continuously traveling web adjacent one edge of said web, and means for notching opposed edges of the traveling web, the notching mechanism rotating continuously about axes parallel to the direction of travel of the web and being so timed as to notch one edge of the web in the space between adjacent ends of the said aligned adhesive stripes as the web is being continuously advanced.

3. In a machine for making envelopes and the like, the combination of a rotary striping device for applying aligned spaced stripes of adhesive along one face of a traveling web adjacent one edge thereof, means rotating about axes parallel to the direction of the web travel for notching opposed edges of the web, the notches in the striped edge of the web being positioned in the space between the adjacent ends of adjacent adhesive stripes, tubing mechanism for tubing the web and to bring opposed notches into juxtaposition in one wall of the tube, and severing mechanism rotated transversely of the web travel for severing the tube intermediate the sides of opposed notches.

4. In a machine for making envelopes and the like, the combination of means for continuously advancing a web of material, notching devices at each side of the advancing web adjacent the edges thereof for notching the web at predetermined intervals, each of said notching devices rotating about an axis parallel to the direction of travel of the web to permit of varying the speed of the web without varying the speed of said notchers thereby to vary the spacing of the notches in the web, means for tubing the web to bring opposed notches into juxtaposition, and severing means for severing the tube transversely intermediate the sides of opposed notches.

5. In a machine for making envelopes and the like, the combination of means for continuously advancing a web of material, notching devices at each side of the advancing web adjacent the edges thereof for notching the web at predetermined intervals, each of said notching devices rotating about an axis parallel to the direction of travel of the web to permit of varying the speed of the web without varying the speed of the notches, thereby to vary the spacing of the notches in the web, and means for tubing the web to bring opposed notches into juxtaposition.

6. In a machine for making envelopes and the like, the combination of means for continuously advancing a web of material, a striping device for applying aligned spaced stripes of adhesive along one face of the advancing web adjacent one edge thereof, notching devices at each side of the advancing web adjacent the edges thereof for notching the web between said stripes, each of said notching devices rotating about an axis parallel to the direction of travel of the web to permit of varying the'speed of the web without varying the speed of "said notchers, to vary the spacing of the notches in the web.

'7. In a machine for making envelopes and the like, the combination of means for continuously advancing a web of material, a circumferentially adjustable segmental disc for applying aligned stripes of adhesive along one face of the advancing web adjacent one edge thereof, notching devices at each side of the advancing web adjacent the edges thereof for notching the web between said stripes, each of said notching devices rotating about an axis parallel to the direction of travel of the web to permit of varying the speed of the web and the setting of said striping disc without varying the speed of said notchers, to vary the spacing of the notches in the web.
