| 摘要 |
The present invention relates to a process for the continuous production of mesh bags (1), comprising the operation of cutting longitudinal portions (2b) from a body of bag formed by a longitudinal section of flattened tubular mesh (3) and a longitudinal section of at least one flexible sheet (4a,4b) applied and attached to one of the faces of said tubular mesh (3), in which prior or subsequent to the application of the sheet on the mesh said sheet is passed through detection means (5), suitable for detecting the passage through the detection field (10) of a section of sheet provided with a marking, transparent to visible light and luminescent upon being radiated with ultraviolet or infrared light. The detection of said marking automatically triggers the performance of the operation of transversely cutting the continuous body of bag into a length corresponding to that of a bag. |
