    • An apparatus for manufacturing a foil web of a thermoplastic with locally secured fittings (21), for use as tarpoulins or similar articles, comprises an extruder head (1) with an entirely or mainly downwards directed ejection orifice and two counterrotating rollers (25, 26) with a nip for calibrating the extruded foil (22). In a feeding device with a vertical supply magazine (10) a stack of fittings (5) is accommodated which by means of a guiding duct (2) may be guided into a discharge duct (3) extending towards the roller nip. The guiding device is electrically operated and an electrically controlled stop member (15) with an associated fitting sensing element (12) are arranged at the lowermost end of the discharge duct (11-15) towards the roller nip (24) for accurate control of the supply of fittings to the roller nip and monitoring the presence of fittings in the discharge duct. The discharge duct is arranged in such a relationship to said counter rotating collers (25, 26) that each fitting is supplied from the mouth of the discharge duct (25) to the roller nip (24) by a substantially free fall.
    • 一种用于制造具有局部固定配件(21)的热塑性塑料制品的装置,其用作纸浆或类似物品,包括具有完全或主要向下定向的喷射孔的挤出机头部(1)和两个反向旋转辊(25,26 ),用于校准挤压箔(22)的压区。 在具有垂直供应料仓(10)的进料装置中,容纳一堆配件(5),其通过导向管道(2)被引导到朝向辊隙延伸的排放管道(3)中。 引导装置是电动的,并且具有相关联的装配感测元件(12)的电控止动构件(15)布置在排出管道(11-15)的最下端朝向辊隙(24),以精确控制 向辊隙供应配件并监控排放管道中配件的存在。 排放管道以与所述反向旋转碰撞器(25,26)相关的方式布置,每个配件通过基本自由的下落从排出管道(25)的口部供给到辊隙(24)。
