ThlS folding block or head l8g1ves the folded 4 paper web a second longitudinal fold, and from this block or head ill the folded web passes between creasing and feeding rollers 2i rotatably supported from the frame H as at 22.

Fig. 2 is a sectional detail view of the same taken substantially on line 2-2 of Fig. 1;

Fig. 3 is a fragmentary sectional detail view taken substantially on line 3-3 of Fig.2; From these folding and creasing rollers 2| the 50 V Fi 4 1s a fragmentary sectwnal f i v w paper web is again folded longitudinally by passof the am ta n s bs t y on 1m of ing the folded web over a third folding block or Fi I I v head 23 supported from a rod 24 in turn supu I Fig. sa fragmentarysectional detail view ported from the frame II as at 25. From this taken substantially on line 5-5 of Fig. 4; folding block or head 23 the folded web is passed construction and operation of the converting mabetween feeding and creasing rollers 28 and 21, the roller 21 being supported in any suitable manner by means of a bracket 28, whereas the roller 26 is adjustably supported by blocks 29 which blocks are slidably mounted upon the brackets 28 and adjusted relative thereto by adjusting screws 3L From these creasing and feeding rollers the paper web, now having been folded into a plurality of coinciding longitudinal folds, is passed through a pair of cutting rollers 32, one of which cutting rollers includes a groove 33 adapted to co-operate with the cutting blade 34 to cut the folded paper web into strips of predetermined lengths.

Co-operating with one of the cutting rollers is a folding roller 35 having a groove 35 formed therein for the reception of the cutting blade 34, and this roller 35 co-operates with the adjacent roller 34' of the cutting rollers 33 for folding the paper web after the same is cut into a strip of predetermined length, transversely upon itself when said strip is fed between the rollers 34 and 35 by means of a feed bar 31 which is supported for reciprocation by means of a suitable bearing block 38 preferably formed as a part of the frame H. The strip after having been given its final transverse fold is delivered from the roller 35 by means of a suitable delivery roller 39 upon which the strip is passed as it leaves the roller 35.

The operation and construction of the converting machine as described is substantially the same as that set forth in the patent herein mentioned, and for a more detailed description of the chine reference may be had to said patent.

The inserting mechanism preferably includes a bracket structure 48 supported from the frame as shown in Fig. 1. Depending from this bracket structure 43 are spaced arms M, which arms support a bar 42 in turn supporting a roll of paper 43. The bracket 40 rotatably supports a printing roller 44 designed to print certain matter upon the paper web as the paper web passes this roller in a manner to be hereinafter described.

The ink is fed to the printing roller by means 1 of feed rollers 45 which feed rollers pick the ink 'passes downwardly between feeding rollers 5H,

passage between the cutting rollers 32, so that from an ink trough supported by the bracket The web 43 from the paper roll 43 passes between the printing roller 44 and a roller 41. From these rollers the paper web is passed over rollers 48 and 49 supported by arms 55 carried by the frame H. From the roller 49 the web 43 which feeding rollers are rotatab-ly supported by means of plates 52 supported from the frame If in a suitable manner.

From the rollers 5! the web 43' passes through a suitable guiding structure 53 which comprises a pair of spaced plates 54 and 55, which guide the paper through the cutting rollers 56 and 5'7, the roller 51 carrying the cutting blade 58 and the roller 56 being provided with the cutting groove 59. These cutting rollers 56 and 5'! cut the web 43 into predetermined lengths, and these lengths pass through a guiding structure GE! similar to the guiding structure 53. From this guiding structure 69 the cut strips are delivered for the strip will be disposed in parallel relation with the longitudinal folds of the web ll.

To assure delivery of the cut strip as cut from the web 43 a feeding mechanism is provided.

This feeding mechanism includes a pair of spaced arms 62 and 62' provided with rings 63 mounted upon eccentric discs 64 fixed upon a shaft 65. Carried by the arms 62 and 62' is a pin 6| on which is mounted a knurled roller 6| adapted to 5 have contact with the knurled surface of the adjacent roller of the feed rollers 32 through a slot 64. formed in an extension 65' of the guiding structure Bil, Fig. 5. The arm 62 is positioned in a recess 66' formed in this extension, whereby 10 to prevent rotation of the arms yet to allow proper longitudinal movement thereof by action of the eccentric discs 64. The arrangement is such that the roller 6| by action of the eccentric discs 64 is brought into contact with the strips 15 r and during that contact this roller with the cooperation of the rotating roller 32 will deliver the severed strip from the web 43 at the proper time so that when the feeding blade 31 operates upon the folded web H, the strip from the web 20 43 will be folded with thesevered strip of the web I! in the manner shown in Fig. 8 of the drawings. The cutting rollers 56 and 51 as well as the shaft 65 are operatively connected by sprocket and chain connections 66 so that these 25 elements will be timed for proper operation whereby to deliver the severed strip from the web 43 to a position to be folded with the longitudinal folded'web H when the same is projected between the roller 35 and the adjacent roller of 3(); the cutting rollers 32, which is the final fold given to the'article converted by the machine.

While we have illustrated and described the preferred form of construction for carrying our invention into effect, this is capable of variation 35* and modification without departing from the spirit of the invention. We, therefore, do not wish to be limited to the precise details of construction 'set forth, but desire to avail ourselves of such variations and modifications as come 40 within the scope of the appended claims.

Having thus described our invention, what we claim as new and desire to protect by Letters Patent is:
