Abstract
A web structure with electromagnetic radiation shifting indicia is disclosed. The indicia provide signals used in controlling various processes to be performed on the web as well as for controlling movement of the web. The preferred indicia are normally essentially invisible so that the physical appearance of the web is not affected. The indicia emit wave-shifted electromagnetic radiation in response to incident radiation of a given range to provide a means for determining the positioning of the web during movement as the processes are performed. Process and apparatus for making and using such webs are also disclosed.
Claims27
An elongated web comprising:
- (a) a pair of plies in face-to-face relationship with one another;
- (b) a visible coating on at least one surface of at least one of the plies;
- (c) said coating being in the form of a repetitive pattern to provide a series of separable web sections;
- (d) the web including a series of spaced, transversely disposed, portions delineating the ends of the sections;
- (e) each of the sections being adapted for separation from the web to provide a commodity substantially identical to commodities formed by separation of the other of the web sections;
- and
- (f) normally invisible, registration enabling indicia on at least one of the plies, the indicia on stimulation by radiation of a given intensity emitting wave shifted electromagnetic radiation of significantly different intensity than that radiated or refelected by the coating and the web plies upon exposure to a given intensity of electromagnetic radiation of a certain wavelength range even though the wave shifted and the radiated or reflected radiations may include radiation of substantially identical wavelengths.

An article for feeding along a path of travel comprising:
- (a) an elongated web having printed locating portions disposed along the web in a repetitive pattern;
- (b) the locating portions normally being essentially invisible such that the web has an appearance to visual observation essentially no different than a web without such locating portions but otherwise identical;
- (c) the locating portions including pigments which are essentially invisible and are responsive to electromagnetic radiation of a given intensity and wavelength range to cause a shift in wavelength of that radiation and to emit radiation in a different wavelength range;
- and,
- (d) the locating portions emissions when exposed to radiation of such given intensity and wavelength range being sufficiently different in intensity from radiated or reflected radiation from other portions of the web when the web is used in an illuminated environment wherein humans are present to enable reliable detection by a detector continuously scanning the web to detect the presence of such indicia while avoiding false detection signals in response to radiated or reflected radiation of the same wavelengths as said different wavelength range, whereby operations performed on the web may be properly coordinated.

An article of manufacture comprising:
- (a) an elongated web having at least one set of repetitive, spaced, transversely extending structurally modified parts such as seals or lines of weakness that physically vary from other parts of the web to adapt the web to be separated into a plurality of like commodities useful in packaging;
- (b) the web having informative printing thereon;
- (c) at least one set of spaced, repetitive indicia on the web, the indicia being spaced along the web;
- (d) each such indicia including transparent, lightwave length shifting particles;
- and,
- (e) the particles having the physical property of being stimulatable by a relatively high intensity electromagnetic radiation of a certain wavelength range and upon being so stimulated emitting relatively high intensity electromagnetic radiation of a different wavelength range, the intensity of said emitted energy in the different range being greater than the intensity of energy in said different range which is reflected by non indicia portions of the web.

- and,
- (f) the colored printing on the web including colors which will reflect ambient radiation of the same wavelengths as the energy in said different wavelength range.
