This invention is an improvementin rotary folding mechanisms for web printing presses and its object is to provide an improved cutting cyl-' V inder having an adjustable circumference so that the peripheral circumference of the collected sections of paper thereon may be kept practically uniform and cause the surface "speed of the outermost sheet of paper collected on the cylinder.
to be the same as the speed of. the paperwebs passing from the former of the folder.
The cutting cylinder is provided with means whereby one or'moresuccessive sheets separate from the web can be collected thereon in accord-' ance with the size of the edition of the paper, difierent editions of the paper varying in the number of pages employed. The cutting cylinder is usually of one fixed diameter or circumference and therefore the thickness of the paper sections collected thereon will vary its diameter according to the number of sections collected thereon. While the paper used is itself of no the number of collected sheets will varyappreciably in various editions, and it is important that the peripheral surface speed of the paper (:01-
lected'on the cutting cylinder should remain practically uniform with that of the web passing from the former regardless of the number of pages delivered to the folding cylinder.
The present invention'provides a cutting cyl-- inder having an adjustable peripheral section which can be adjusted in-or outto increase or diminish thecircumference of the cylinder, in accordancewith the number of sections of paper to be collected thereonj 'so that whatever given number of sections are collected thereon the exterior peripheryorcircumference of the outermost sheet of paper thereon will be such as will cause the peripheral speed-of the paper on the cutting cylinder to equal the speed of the paper delivered to the folder.
the accompanying drawings I have illustrated the invention as applied to a well known type of rotary folder and'will'explain the same with re'ference thereto and then set forth in the claims the novel features and combinations of parts for' whichprotection is desired. In said drawin'gsw w i, Fig. 1 is adiagramrhatical part sectional elevation of a rotary-folder having a cutting cylinder constructed in accordance with my invention; I
Fig. 2 is a side view of such folder partly broken away, the paper delivery mechanism being omitted;

Fig. 4xis an end view of thecutting cylinder detached;
Fig. 5 is a detail plan view of the right .hand end-of the cutting cylinder. i
. The cutting cylinder 1 and folding cylinder 2, may be mounted as usual on shafts 1a, 2w, journaled in hearings in suitable framing and provided with the .usual cutting devices 1e, 2e. The cylinder 2 is provided with the usualpin operating devices, indicated at 2b2c in the drawingsywhile cylinder l'is provided with'the customary pin operating mechanism, indicated at 1b, for collecting sections of paper. 2 is alsoprovided as usual with two rotary tuck 'ing blades 3, which are diametrically opposite and mounted on shafts 3a journaled in bearings 4a attached to rocking plates 4 rotatably mount. ed upon the shaft 2a. All these parts are-well known and need-no specific explanation or illustration. q 1 V V The web comingfromthe printing press is led over the. usual former 7 by which itis given its first longitudinal fold, and is then passed between the first folding rolls 7a andv 7b to'and between thecylinders 1 and 2, being severed into sections of sheet lengthby the'cutting blade 1ecooperating with the cushion '2e at the proper time. When the sections areto be collected, the leadingvedge of the severed'section is engaged by .the collecting pins 1d so'that the sectionis wrapped'around the cutting cylinder 1. One or more sections may be successively collected on the cylinder 1 as desired... At the proper time. thecollected sections are :released .by the pins 1d and engaged by collecting pins 20 on the folding cylinder 2 which also engages the following section; andthe collected sections-on cyl inder v2 are then tucked by. a tucker 3 between the second-fold rolls 8 and 8a.; the collected sheets being tucked'betweenlthe second fold rolls i in the usual manner, as will be readily. under:- stood-by pressmen. Roll 8a is usually mounted in swingable arms on a rock shaft 8b yield-1 inglypressed by springsSd strung on a rod 8f passing through an eye bolt 8e. Fromthe second fold rolls'the papers are directed by the.
which they are delivered from the press. 'L 1 In the present invention the cutting cylinder Cylinder 1 is. provided with a peripheral longitudinal rerelatively to the surface of the cylinder 1 by the; engagement of the inclined faces of the projections 1 and 5e.
The plate 5 may be longitudinally adjusted and secured in adjusted position by any suitable means. is provided at one end with an'inwardly extending projection, which is shown as a plate 5a secured to the end of the segment 5 by bolts 5c;
This plate 5a has a slot in its inner end through which" passes a bolt 5b' which'is provided with a collar 51 to engage the inner face of the plate (see Fig. 3) and when thebolt is turned the plate 5 will be moved longitudinally of the cylinder 1; To secure the segment in adjusted position bolts 5d are tapped into the projections 17 and pass through slots 53 in the projections 5e; the heads of such bolts being concealed in recesses 51% in the outer surface of the segment.
If it is desired to diminish the circumference of the cylinder 1, segment 5 should be adjusted to the left; to do this the bolts 5d are loosened and then the segment adjusted by turning screw 5d until it .is in the desired position; then the segment is fastened by tightening the bolts 5d. If
it is desired to increase'the circumference of the cutting cylinder, segment 5 should. be adjusted to the right, which would cause its periphery to project more or less beyond the periphery of the cylinder 1 and thus increase the circumference of the latter.
By means of this adjustable segment the'circumference of the cutting cylinder 1 can be readily increased or diminished as desired, inaccordance with the number of paper sections to be collected thereon, so that the exterior circumference of the sections collected on the cylinder shall be such that the peripheral surface speed of the paper sections on the cutting cylinder will exactly equal the speed of the. paper web passingfromthe former thus insuring .uniform andcorrect final folding of the collected papers when tucked between the final fold rolls 8 and 8a.
I do not limit my invention to the exact forms shown in the accompanying drawings for obviously changesmay be made therein within the scope of the claims. I
I claim:-
1. A-cutting cylinder having a longitudinal peripheral recess, a rigid segment in said recess, 1
and means for adjusting the segment to cause its bodily projection or retraction radially of the cylinder. V
2. A- cutting cylinder having a longitudinal recessand inclines in said recess; a rigid segment in said recess having inclines engagingthe inclines in the recess; the inclines being adapted to cause the bodily projection or. retractionof the segment, and means for securing the segment in adjusted position.
