[1] [2] In addition to cutting the small-grain crop, a binder also 'binds' the stems into bundles or sheaves. These sheaves are usually then 'shocked' into A-shaped conical stooks, resembling small tipis, to allow the grain to dry for several days before being picked up and threshed. Withington's original binder used wire to tie the bundles.
This binding is great for annual reports, owners' manuals and software manuals. Wire bound books are made of individual sheets, each punched with a line of round or square holes on the binding edge. This type of binding uses either a 3:1 pitch hole pattern with three holes per inch or a 2:1 pitch hole pattern with two holes per inch.

The wrapping machine may be pulled by hand using a rope from the ground or it may be self-propelled and radio controlled. Motive power may be provided by a petrol engine or a battery pack.
