A method of spraying patterns on a web that includes directing at least one intermittent spray of liquid onto the web to form a pattern on the web; sensing a position of a leading edge of at least one of the spray and the pattern relative to one or more references on the web; generating a first correction signal when the leading edge is out of position; and adjusting the spray of liquid in response to the first correction signal to correctly position a leading edge of a subsequent pattern. The method further includes sensing a position of a trailing edge of at least one of the spray and the pattern relative to one or more references on the web; generating a second correction signal when the trailing edge is out of position; and adjusting the spray of liquid in response to the second correction signal to correctly position a trailing edge of subsequent patterns.

Methods for applying a liquid to a web

A closed-loop system can maintain a pre-set cut length of a material as the material is cut and placed on a web. The system has the ability to measure the actual cut length, compare the average actual cut length to a target cut length, and to adjust web tension or feed roll speed to achieve the target cut length. Actual cut length variation is thereby reduced. Furthermore, short term cut length variation is further reduced by minimizing the tension of the web just prior to the material being cut.

System for measuring and controlling cut length of discrete components in a high-speed process

A system and method for detecting a registration mark associated with an object which provides improved resolution between matching and non-matching inputs. The registration mark represents a binary code sequence. Upon detecting a sequence of bits with a sensor, the detected sequence is provided to a code matching filter, which compares the detected sequence with the binary code sequence and produces a detection signal. The code matching filter increases a value of the detection signal for each matching pair of compared bits, and decreases the value of the detection signal for each non-matching pair of compared bits. In this manner, a penalty is assessed for mismatches. This results in a filter output having a high amplitude in response to a matching input, and a low amplitude for non-matching inputs. The system may sample the detected sequence of bits in such a manner as to avoid potential edge timing problems.
