Ribbon for e.g. bounded book, has needle that is designed in such a manner that thread guide runs transverse to needle body, so that needle exhibits T-shape, through which band is doubly led

摘要

The ribbon (A) has a sphere (B) and a lens including a hole centrically, through which the ribbon is doubly led. The ribbon is a flexible band, which is made up of natural or synthetic fiber. A needle (E) is designed in such a manner that a thread guide runs transverse to a needle body, so that the needle exhibits a T-shape, though which the band is doubly led.
