ABSTRACT:
An improvement on commerical machines which bind documents using plastic strips. The punch mechanism may be automatically actuated when the paper sheets are properly aligned on a punch platen or actuated manually at the user's discretion. Distance of the holes from the edges of the sheets may be indexed. The binding mechanism improvements include interchangeability of height of the pressure bar and speed of binding mechanism, depending on thickness of book to be bound or as selected by user, means for automatically starting the motor drive of the binding mechanism and pressure bar when it has been manually placed or moved onto the document to be bound, automatic lifting of the pressure bar when the binding cycle has been completed, a resistance-heated knife construction which reaches operating temperature more rapidly, controls and minimizes the heated knife temperature fluctuations, maintains a more uniform temperature profile of the knife, improvements in the mounting of the timing cams of the machine and improved means for securing and positioning the cooling and forming fingers in place. In a modification, means is provided for binding a "wrap-around" cover which extends rearward of the spine of the book and then is folded forward around the binding strips for the book. The means comprises a removable backstop for the spine edges of the sheets to be bound, a platen and roller to support the lowermost of the wrap-around covers and a rack to support the uppermost of the wrap-around covers during the binding procedure. The knife structure is modified to avoid interference with the modified means.
