1,231,013. Nets. UNION CARBIDE CORP. 10 July, 1968 [10 July, 1967], No. 32789/68. Heading D1R. R. A netting machine comprising substantially parallel rows of advancing loop-receiving pins 28 which support the netting 31 also comprises a means 90 to reduce the mesh. .size of the netting. This means comprises (a) a pair of spaced endless transfer means each having a portion thereof located just inside one of the rows of pins and extending in the direction of advance of the netting and supporting the selvage of the netting and (b) a loop-stripping means for removing selvage loops from the pins 28 while the netting is being received by the endless transfer means 90. The endless transfer means is advanced at a speed less than that of the advancing pins 28 to reduce the size of the mesh. In a first embodiment (as shown) the endless transfer means, Fig. 3, comprises upper and lower belts 66, 67 having mating stretches for nipping the selvage of the netting. The loop stripping means then comprises strand cutters 90 mounted .immediately behind the nip of the belts 66, 67. In a second embodiment, see Figs. 4 and 5 not shown, the endless transfer means comprises a flexible finger-carrying belt which is mounted at its ends around rotatable members which rotate in a plane normal to the netting. As the finger-carrying belt passes around the rotatable member, each successive finger enters the selvage loops on the advancing pins 28 and lifts the loop off the pin. The fingercarrying belt has a straight stretch and travels at a lesser speed of advance than the pins. |
