DESCRIPTION:

BRIEF SUMMARY
BACKGROUND OF THE INVENTION

This invention is concerned with improvements relating to binding machines, particularly of the kind (hereinafter referred to as being of the kind specified) for binding packets having a row of apertures or perforations adjacent to one side edge, by the use of and a binding element (conveniently termed a "comb") comprising a spine and a series of curved, flexible fingers which may be located in the apertures of the packet, to bind the sheets of the packet together into book-like form.
Difficulty is encountered in the provision of a machine of the kind specified, which will clamp the binding element in a convenient position, and straighten the fingers to allow them to be inserted into the apertures of a stack, during a binding operation.


SUMMARY OF THE INVENTION

According to this invention there is provided a binding machine of the kind specified comprising clamping a mechanism to clamp a binding element and an operating member operative to cause the fingers of the binding element to be uncoiled, the clamping mechanism being moved to an operative position prior to movement of the operating member to so uncoil the binding element.
Preferably the clamping mechanism is operative to clamp the binding element at a plurality of spaced positions, preferably said positions being spaced a distance equal to the spacing between the fingers of the binding element.
Preferably said clamping is effected under the action of a spring. Thus, advantageously, the clamping mechanism comprises clamping elements which are urged by the action of a spring into engagement with fixed abutment elements.
Preferably the operating and clamping mechanisms are moved by a single olive mechanism, such as a rack and pinion. Thus advantageously the machine comprises drive means to so effect movement of the operating and clamping mechanisms.
Preferably the operating member comprises a plurality of fingers, the operating member being so constructed and arranged that on movement of the operating member to an advanced position, said fingers move initially laterally to positions in which they engage within the coiled fingers of the binding element, and then longitudinally to unwind the coiled fingers, preparatory to insertion of the uncoiled fingers into the apertures of the packet to be bound.
According to this invention there is also provided a binding machine of the kind specified comprising retracted position and an advanced position, in which advanced position clamping elements of the clamping member are disposed closely adjacent to abutment elements; and in a second direction to an advanced position; and position, the clamping member is moved to its retracted position and the operating member to its retracted position, and on movement of the drive member to its advanced position the clamping member is moved to its advanced position to clamp the binding element and the operating member to its advanced position, fingers of the operating member moving first laterally to a position adjacent to the fingers of the binding element, and then longitudinally to uncoil the fingers of the binding element.
Advantageously the operating member comprises a plurality of fingers, each finger comprising a longitudinal portion and a transverse portion, lateral movement of the operating member causing each of the transverse portions of the fingers to engage within a coiled finger of a binding element clamped by the clamping member, and longitudinal movement causing the transverse portion to unwind the coiled finger.
Advantageously, means is provided which is operative on initial movement of the drive member from its rest position to cause the operating member to move solely laterally, and further means operative subsequently to cause the operating member to move solely longitudinally.
