Title: Methods and systems for operating control of the functional film layer containing detectable component
Inventor: DZHONS DEVITT
IPC: B29C48/92
Filed: 2018-02-08
Granted: 2021-02-10
Abstract: FIELD: technological processes. 
     SUBSTANCE: invention relates to a method of estimation of continuity of a functional layer of material. The technical result is achieved by way of estimating continuity of the functional layer of film which includes forming a sheet by extrusion of thermoplastic material through a ring matrix producing ring tape, hardening said tape and flattening into a flat configuration which will further be used for manufacturing multiple packages. The sheet is moving at a speed of five meters per minute. The functional layer of the sheet contains a mixture of a thermoplastic composition and a detectable component which is contained in the thermoplastic composition on a level detectable in the functional layer of the sheet. Detection of the functional layer and discontinuities of the functional layer is conducted through control of the sheet by a computer vision system capable of detecting presence or absence of a detectable component in the functional layer of the sheet. Control is implemented by scanning the shield in movement and in flat configuration. Scanning is conducted via a camera located (i) downstream from the point where the tape is hardened and flattened into a flat configuration, (ii) downstream from the point where the solid ring tape undergoes orientation forming ring sleeve film, (iii) upstream from the point where the ring tape is spooled up and cut, and (iv) in the sheet scanning position prior to the product being put into a package. At the same time, a signal is generated as a response to detecting a discontinuity in the functional layer. 
     EFFECT: increased speed and efficiency of testing for discontinuities of film layers without interruption of film manufacturing process and without destroying any parts thereof.
