Abstract

An apparatus and method for marking a web at a selected location along its length. A coil is rotated on its axis to wind the web thereon and draw the web into the coil along a predetermined path. A flat marker is fed between the incoming portion of the web and the coil codirectionally with movement of the incoming portion so that a surface of the marker confronts and engages a surface of the web. Preferably, a marker having an adhesive face is fed so that such adhesive side engages the incoming portion of the web.

Claims

1. Apparatus for marking a web comprising:

(a) takeup means for supporting a takeup coil and rotating it on a fixed axis to draw a web longitudinally onto the coil along a predetermined path; and

(b) selectively operable marker dispensing means for feeding a flat adhesive marker into the space between the incoming portion of the web and the coil, said marker dispensing means including;

a rotable shaft disposed at an oblique angle relative to the plane of the surface of the incoming web;

a cross member secured to said shaft having a plurality of tines mounted thereto, said tines having marker engaging surfaces thereon for engagement with the adhesive side of the marker; and

,

means for rotating said shaft from a position whereat said marker engaging surfaces are alongside the web for securing a marker to said tines, to a position whereat said marker engages the surface of the web for placement of the marker on the web, the oblique placement of said shaft causing said tines to move in a bi-directional path relative to the surface of the web such that as the marker approaches the web, it is moving toward the web and in the same direction as web movement.

2. Apparatus as claimed in claim 1 wherein said marker dispensing means is arranged to feed the marker so that the marker will engage the incoming portion of the web before it engages the previously coiled portion.

3. Apparatus as claimed in claim 2 wherein said marker dispensing means includes means for holding a marker having an adhesive face while such marker is being fed so that the adhesive face of the marker will confront the coil facing surface of the incoming portion of the web.

4. Apparatus as claimed in claim 3 wherein said marker dispensing means is disposed on the coil side of the incoming portion of the web, said tines having marker engaging surfaces facing away from the incoming portion of the web, so that when a marker having an adhesive face is engaged with the marker dispensing means by applying a portion of such face to the marker engaging surface of said tines, the adhesive face of the marker will face toward the incoming portion of the web.
