Going back 50 years, I used to use a large loose leaf book, the outer
being two thick black boards, the two joined by a pair of thick straps.
One outer had a key hole, the key being cranked, and operation of the
key caused the straps to be drawn into the cover.Â* Pages had a special T
shaped cut out, which was arranged around the straps, the key operated
which tightened the straps, securing the book.Â* Unwinding the key
released the straps, enabling new pages to be added or old ones replaced.

What I can't remember is how the cut outs were formed in each sheet of
paper.Â* Presumably something like a standard hole punch, but larger.

My Google-fu is having a day off.Â* Any idea what that type of binder was
called?


I vaguely remember something like that. They were very fiddly to
reassemble as I recall. The boards/covers were in two pieces, one was
narrow (may be 1cm ) and the rest a little under A4 (or may be foolscap
in those days!). The holes for the binding part were in the narrow bit
and the two parts were held together by a cover made of a cloth like
material to form a hinge.

There was another, simpler, system, which used a spring link thing which
went through the holes in the paper and covers (just normal round holes)
and then there was a metal part which the ends tucked under.

From memory, they were used in part of a Company worked in as a Vac
student in the mid/late 70s. Possibly another part of the same (overall)
Company I joined on graduating in '79.

As for the name/make- no idea, they were just a stock item in the
stationary cupboard and you asked the Stationary Overlord for one,
pledged the blood of your first born etc ...at least unless they needed
a radio fixing ;-)
