Abstract
A web of pouches is fed past a detector. Inflating mechanism inflates individual pouches to create individual profiles. The detector responds to the appearance of a preselected distance between the surface of the pouch and the detector as each pouch passes the detector.
Claims5
Apparatus for registering pouch seals on a web of pouches comprising:
- means for forming a continuous, substantially two-dimensional web of vertically-oriented pouches having open upper ends, said pouches being delineated by spaced vertical seals,
- pneumatic means for opening said pouches to create a discernible profile,
- means for reading the profile of each pouch and seal,
- means for cutting said web on each said seal,
- and means for controlling said cutting means as determined by said profile reading means, thereby causing said web to be cut at approximately the center of each seal.
2 more elements
Apparatus for detecting the position of each transverse seal on a web of interconnected, substantially two-dimensional pouches comprising:
- means for inflating each pouch to create a discernible profile,
- means for confining the lateral extend of bulging of inflated pouches,
- and a detector sensitive to changes in the lateral profile of the pouches mounted on said confining means and directed at the side surfaces of said pouches,
- said detector generating a signal when a preselected distance of pouch surface to detector passes said detector.
