B AGE/vr LUnited States Patent Office 3,462,093 laten'tedv Aug. 19, 1969 U.S. Cl. 242-56.2 31 Claims ABSTRACT OF THE DISCLOSURE An apparatus for winding and cutting a predetermined length from a continuously fed web having succession of like designs or indicia thereon such that the cut is inregister with the design or indicia. A pair of web winding mandrels are rotatably mounted on a rotatable turret t receive the web after it has been printed; the turret being in turn mounted to index each mandrel between a starting position where the previous running web is cut and the rest of the web is started upon a fresh mandrel, a winding position where the major portion of the web is coiled upon the mandrel, and an unloading position where the finished coil is removed from the mandrel. The mechanism of the apparatus is driven through a plurality of interconnected planetary drive systems such that the feed of the web upon the mandrel is synchronized with the input from the press upon which the web is being printed, with the movement of the turret upon which the mandrel is mounted, and with an enveloper mounting the web cut off mechanism; such that these various mechanisms are driven in synchronism with each other. The web winding mandrels are formed in two sections each with cooperating cam surface biasing substantially the longitude and the length thereof with one section mounted for slidable movement upon the other along the cam surface, with both sections normally forming opposed circular sections of a given diameter, and with both sections cooperating with means operable upon operation of the turrets to a given index positions for displacing same along the cam surface to reduce the diameter of the sections. Appropriate electrical circuitry is provided to facilitate the operation of the various elements of the mechanism and for providing a count to signal and control operation of the cut off 4mechanism so as to precisely cut the web between successive indicia.

BACKGROUND OF INVENTION This invention relates to improvements in apparatus for the slitting and winding into coils a relatively wide web of paper or other sheet material into a number of relatively small and narrow rolls. More particularly, the invention provides improved means and method for automatically winding upon an arbor or :mandrel `a plurality of web strips, such as well known trading stamps, to form a plurality of rolls thereof comprising in length a predetermined number of stamps and in which any roll may be of a preselected number of stamps in width.

Where webs characterized by repeated impressions, such as trading stamps or the like, are to be formed in continuous manner into separate rolls having a preselected number of stamps to the roll a problem is presented, in that, not only is suitable control and counting means required for determining when a proper number of stamps are wound to complete the roll, but also special means are required capable of severing the web at a precise impression junction in separating a final stamp of the completed roll from the rst stamp commencing a new roll.

An object of the present invention is to provide improved means for automatically winding a web to continuously form rolls of predetermined size and which are accurately cut olf at a precise count line.

Another object is to provide means for forming successive rolls of web of a predetermined size Without interrupting the winding operations.

Another object provides means for effecting continuous coiling operations to a web which may enter the coiler in either an intermittent or continuous feed manner.

Further, the invention includes Imeans for automatically modifying the speed of the Winding machine to thereby correct an advancing speed of the web to synchronize with the web feed speed as entering the winding machine.

Another object of the invention is to provide improved cut-off devices which in a continuous web feeding operation accurately sever the web ribbons on the fly yand direct the severed ends thereof about a new mandrel.

Another object is to provide control :means for determining operation of the severing means in accordance with a preselected number of stamp counts comprising a complete roll.

A further object includes means for synchronizing a web cut-off movement of the severing means to the surface speed movement of the web.

Special ribbon spreading means are also provided for sep-arating longitudinal edges of adjacent webs incident to web slitting operation.

As another object the invention provides control devices timing the severing operation to effect an accurate cut-off of the webs relative to any given line separating a stamp impression from a succeeding stamp impression along the web.

As a further object the invention includes in the timing control a means operable as timed by the web in accordance with a perforated pattern therein whereby to count the number of stamp impressions comprising a roll and to determine exactly where the web must be cut off.

Yet another object of the invention provides improved spindle means for winding the web and which permits an easy removal of a completed web roll therefrom.

Still another object provides for mounting the spindle upon a turret adapted to be indexed to successive control positions for displacing a completed web roll to a takeoif position and for bringing a new spindle into position for receiving the incoming Web.

The invention also provides special means for constantly maintaining surface speed of the web substantially uniform throughout the roll winding operations.

As a further object the vinvention includes means for maintaining winding surface speed of the web constant during any displacement of the web roll spindles incident to indexing movements of the turret support therefor.

IN GENERAL The coiling machine of the present invention is designed for slitting and rewinding into separate adjacent coils of various widths a web of standard size trading stamps; which normally include twenty stamps across the web.

The machine -may be used for Gif-press work wherein a web may be fed in a continuous manner from a parent roll or may form an attachment to any of the wellknown stamp printing and perforating machines, which may include intermittent feed means and any suitable counter mechanism, such as the well-known Veeder counter disclosed in U.S. Patent No. 2,799,740 issued July 16, 1957 to F. T. Blackman and U.S. Patent No. 2,628,799 issued Feb. 17, 1953 to H. N. Bliss, to effect a count for each printing stroke corresponding to a ten stamp impression processed along the web during each cycle of machine operation.

In the illustration given, and with particular reference to FIGS. 1-1A and 9 for an initial webbing up operation the web W enters the coiler through a dancer comprising spaced tension control arms 1 fast on a shaft 2 pivotally mounted upon the framing 3 of the coiler machine. Supported for rotation upon the distal end of movable arms 1 are three spaced rollers 4, while pivoted upon a fixed bracket 5 (FIG. 1A) is a pair of spaced rollers 6. For off-press work, where web W is drawn off a suitable storage drum in a continuous manner, the web is fed beneath rollers 4 and up over an idler roller 7 mounted upon the pivot shaft 2 of dancer arm 1. For on-press work, in which the web is fed to the coiler in intermittent manner from a press, the web is first wrapped successively around the rollers 4 and 6 as shown in FIG. 1A and thereafter up over the roller 7.

A light infeed web tension between the press and the coiler may be attained by attaching a suitable spring 7' (FIG. 9), of more or less force as required, to the dancer shaft 2. The dancer 1 is limited to a short oscillating excursion sufficient for operating a pair of micro switches S10 and S11 controlling a jogging or correction motor 40 (FIG. 1l) which speeds up or slows down the coiler so that it will stay in step with the press machine. When the coiler winds faster than the press delivers the web the upstream correction switch S10 is operated by the dancer 1 and motor 40 operates in a direction to slow the coiler down. On the other hand if the dancer operates the downstream switch S11, the correction motor runs in a direction to speed up the coiler. The correction motor 40 runs only long enuough for the coiler to again be brought into synchronism with the press.

To initially thread the coiler about ten to fifteen feet of leading web is preliminarily advanced from the press to the dancer 1. Then from the dancer the web W is threaded around a guide roller 8 (FIG. 1) clockwise, thereafter from the bottom up counterclockwise around a tension drag roller 9, clockwise around a guide roller 10, around a portion of a cylinder 11 having pins 12 for engaging suitable perforations of the web, over the top of a guide roller 13 for holding the web around pin cylinder 11, under an input roller 14 associated with a web slitting assembly, thereafter between the slitting knives 16 and associated score cylinder 17 of said assembly, now around a special convex ribbon diverging output roller 18 of the slitter assembly, past suitable ribbon tension equalizing shoes 19, around a concave roller 20 for spreading the ribbons, over the top of a ribbon spacer guide roller 21 mounted for clockwise rotation upon a turret 22 which is supported for counterclockwise rotation upon shaft 23, and thence over the top of a spindle 24 and a fixed rod 2S in the turret 22, and on to a second spacer guide roller 21 and spindle 24.

Associated with each spindle 24, 24 is a follower roller 25, mounted on a corresponding arm 26 pivotally mounted at 27 upon turret 22 and connected by link 28 to a spring tensioned arm 29, pivoted upon the turret at 30. By lifting the related follower roller 25 the web may be manually wrapped around spindle 24' and after releasing the follower the spindle may then be power driven counterclockwise to wind a few turns of web thereon by special jog drive controls operating motor 40 (FIG. 11), as in the manner and purpose hereinafter described.

During the above initial webbing up operation the slitter knives 16 are usually withdrawn, so that the coiler is now webbed up and ready to run with a full or unslit web. The slitting assembly is of well-known design and it is suiiicient at this time to say that a desired number of knives 16 are inserted to accord with the number of stamps to the width of each coil to be simultaneously wound upon spindle 24.

As will become more apparent as the description proceeds, the intended mode of operation is to automatically start the winding of any new roll upon the upper spindle 24 during a completion of a preceding roll upon the lower spindle 24. Special cut-off means being provided for automatically severing the web at a precise point separating indicia on a new roll from the old, in accordance with the manual setting of a preset count control means for determining the desired number of stamps required for the completed rolls. v

Following such severing of the web, lower spindle 24 continues only a few more turns and will then stop, while upper spindle 24- will continue in its winding operation. Thereafter turret 22 is caused to be automatically rotated in a counterclockwise indexing operation, bringing spindle 24 from the winding position indicated in FIG. l to an intermediate position indicated as Athe unloading position in said ligure. Thus at this point in the webbing up operation an operator now removes the paritally cornpleted roll and immediately engages a control switch which causes the turret 22 to again rotate until the upper spindle 24 is brought to the winding position while the spindle 24 is moved to the upper starting or cut-off position ready for receiving a new roll of stamps.

After the above initial webbing up operation a number of preliminary short coiling runs may be made for checking and to make any necessary adjustments and if the
