一种塑料或类似材料的加强套，用于硬纸卷芯或类似物的端部，所述硬纸卷芯或类似物形成卷绕物品如纸、箔、纺织品或类似物的支撑芯。套筒包括适于抵靠卷轴芯的端面的轴环和与轴环和套筒的外周成一体的径向中空突出部，突出部适于接合卷轴芯的一个端面并容纳驱动器系统。加强环集成在轴环中并且包括用于驱动器系统的径向延伸的接收元件，接收元件集成在径向突出部中并且加强径向突出部。
A reinforcing sleeve of plastic or a similar material for the ends of hard paper reel cores or the like which form the support cores for wound goods such as paper, foils, textiles or the like. The sleeve comprises a collar adapted to rest against the end faces of the reel core and a radial, hollow projection integrated with the collar and the outer periphery of the sleeve, the projection being adapted to engage one end face of the reel core and to house a driver system. A reinforcing ring is integrated in the collar and comprises a radially extending receiving element for the driver system, the receiving element being integrated in the radial projection and reinforcing it.
