    摘要： This invention relates to a nonadjustable multispindle drilling assembly for drilling holes in rewind roll cores for receiving drive pins for a first standard diameter rewind roll core and for a second standard diameter rewind roll core, the combination including a first group of a preselected number of spindle assemblies mounted to correspond to the first standard diameter core and a second group of a preselected number of spindle assemblies mounted to correspond to the second standard diameter cores, each of the spindle assemblies being driven by a drive pulley mounted thereon which is driven by an endless timing belt, all of the spindle assemblies being driven in the same direction and at the same rotational speed.
