纸塑复合放收卷是该复合加工过程中运行的始与末两个端点。其中 ,放卷指的是涂覆辊组牵引作用下塑编布卷、纸卷等连续放送运行的起始端 ,而收卷则指涂覆辊组和同步连动机械作用下纸塑等复合布被收卷辊组中收卷轴管连续卷绕成复合卷的运行末端。该放收卷物理量的控制 ,如卷重（ Paper and plastic composite release volume is the beginning and end of the composite processing operation of the two endpoints. Among them, the unwinding refers to the coating roll under the action of plastic woven cloth rolls, rolls and other continuous start running, while the winding refers to the coating roll group and the simultaneous action of paper and plastic and other composite machinery under the action It is wound up by the take-up reel to rewind the running end of the composite roll. The volume of the physical volume control, such as volume weight (
