Method and apparatus for controlling the cutting and placement of components on a moving substrate
First Claim
1. An apparatus for selectively providing predetermined segments of web material, comprising:
- supplying means for providing said web material;
first sensing means for detecting a reference marker on said web material and for generating at least one reference marker datum which is associated with a selected web segment;
separating means for providing at least one separation datum and for dividing said web material along a separation region to provide said web segment;
phase regulating means for controlling a relative phasing between said reference marker detected by said first sensing means and said dividing produced by said separating means, said phasing controlled with respect to a set reference value;
assembling means for placing said web segment onto a substrate;
second sensing means for separately detecting a location of said separation region relative to said reference marker to generate at least one location datum;
data processing means for evaluating said location datum to generate an updated set reference value; and
set reference regulating means for selectively adjusting said phase regulating means to incorporate said updated set reference value.

Abstract
A distinctive apparatus and method for selectively providing predetermined segments of web material comprises a supplying mechanism for providing the web material. A first sensing mechanism detects a reference marker on the web material to generate at least one reference marker datum which is associated with a selected web segment. A separating mechanism includes a sensor mechanism for providing at least one separation datum, and divides the web material along a separation region during a production of the web segment. A phase regulating mechanism controls a relative phasing between the reference marker detected by the first sensing mechanism and the dividing by the separating mechanism. The phasing is conducted with respect to a set reference value. An assembling mechanism places the web segment onto a substrate, and a second sensing mechanism separately detects a location of the separation region relative to the reference marker to generate at least one location datum which is in correspondence with the separation datum. A location correlating mechanism generates at least one comparison datum associated with a web segment, and a data processing mechanism evaluates the comparison datum to generate an updated set reference value. A reference regulating mechanism selectively adjusts the phase regulating mechanism to incorporate the updated set reference value.
