Abstract

The photoconductor web of a drum-type xerographic device is wound onto the drum's supply spool by means of a web path which allows the operator to properly attach the web's leading end, and to thereafter visually monitor proper winding.

Photoconductor Winding

The photoconductor web of a drum-type xerographic device is wound onto the drum's supply spool by means of a web path which allows the operator to properly attach the web's leading end, and to thereafter visually monitor proper winding.

In Fig. 1, reference numeral 10 identifies a large spool of photoconductor web 19 which will be unwound onto a number of smaller supply spools 11, the later ones of which will be thereafter mounted as supply spools inside a xerographic drum, such as is described in U. S. Patent 3,558,242, for example.

The operator manually threads the web through the path established by rollers 12-17, and then tapes the end of the web to metal supply spool 11.

Rollers 15-17 are constructed as shown in Fig. 2. Each of these three rollers includes a center portion 18 which is of reduced diameter, and is of an axial length only slightly greater than the width of web 19. The walls 20 of each roller are perpendicular to the roller's axis. Since the operator must thread the web through rollers 15-17, such that the web engages the center portion 18 of each roller, the web end is properly aligned for taping to spool 11.

Spool 11 is thereafter driven, as shown by arrow 21, and a portion of the web is wound onto the spool, whereupon the web is cut, and another spool 11 is mounted for winding.

As winding progresses, the operator observes the web as it runs in the center portion 18 of rollers 15-17. If the web begins to move to the side...
