  • Patent number: 4927310
    Abstract: Male and female book binding strips are packaged in cassettes and the respective cassettes are stacked in male and female hopper stations. Punched sheets are deposited in a staging station. The components of the book are then assembled in an assembly station. Thus the stack of sheets is fed onto one jaw and one male strip is fed onto that jaw while a female strip is fed onto the opposite jaw superimposed above the first-mentioned jaw. The two jaws are moved toward each other until the stack is loosely held therebetween. Thereupon the jaws are pivoted to vertical position, the stack resting on a base plate attached to one one jaw. The stack is jogged so that the holes in the sheets are aligned with each other and with the holes in the female strip. The male strip is pushed inward toward the stack, the studs fitting through the holes in the sheets and through the female strip.
