A helical coil is inserted into holes at an edge of a book by a machine which is adjustable for different diameters of coil. The face of the book sits on a platen and the coil is driven by a roller while the edge of the book is supported on a plurality of spine formers having an arced surface for shaping the edge of the book and an end of the book is engaged by a side lay member at an angle to incline the holes at the angle to receive the turns of the coil. The flat spine formers are carried on supports which rotate so as to allow the turns of the coil at the pitch angle to pass the spine formers. For different book thickness and coil diameter, the arced shape of the spine formers, the spine former angle and the lay angle are changed manually.

Bookbinding by inserting a helical plastic coil into the aligned holes at the edge of the book

A helical plastic coil is used for binding a collated book having a stack of pages with aligned holes along one edge of the book where a leading end of the filament is fed into a first hole at a first end of the book and the coil is rotated about its axis such that the leading end is threaded through the holes by entering each of the holes until the coil is threaded through all of the holes. The leading end of the coil is sheared by an anvil and blade so as to define a leading apex and a leading surface inclined rearwardly from the leading apex along the filament and across the filament. The leading apex is arranged such that, as the leading end enters each of the holes in turn, the leading apex is located on the leading end of the filament at a position thereon facing away from the trailing end of the coil and spaced from the end of the hole facing the first end of the book.

Method for binding a book with a helical plastic coil

A machine for cutting and crimping the ends of a helical coil inserted into holes at an edge of a book to hold the coil in place is adjustable to accommodate different diameters of coil. A guide member for centering the axis of the coil in a centering direction is adjustable to accommodate different diameter coils and for adjusting the location of the axis in an adjustment direction at right angles to the centering direction depending upon the diameter of the coil. A cutting device has a blade movable in a slot of an anvil to shear on one side and to bend on the other side to form a crimped end portion. The adjustment of the axis causes the cutting device to cut the end portion longer for larger coils. The cutting device is adjustable to rotate the anvil relative to the axis to accommodate different helix angles.

Bookbinding coil end cutting and crimping machine

A machine for inserting plastic pre-formed helical coils into aligned holes at an edge of respective collated books for binding the books is adjustable to accommodate different thickness books and respective different diameter and pitch of coil. The machine has a platen having an edge comb at which the edge of the book is presented and a coil drive for rotating the helical coil parallel to the edge of the platen. Two spine formers support the book such that its spine takes up a curved shape in side elevation and a clamp with an edge comb clamps the book on to the platen. Both the edge comb of the platen and of the clamp are provided as insert portions attachable to the respective element for easy replacement of the pitch. The location of the coil drive is automatically adjusted by measuring the coil diameter with a gauge. The clamp moves along an arc which automatically adjusts the clamping location for thickness of the book.

Bookbinding coil insertion machine

A machine for forming helical coil comprises an elongate cylindrical mandrel which is rotatable about its longitudinal axis, a stationary helical guide coil wrapped around the mandrel and defining a helical guide path around the mandrel between turns of the guide coil into which path the material is guided. At least two drive rollers parallel to the axis of the mandrel which are rotatable each about a respective longitudinal axis. A drive coupling member at one end of the mandrel for receiving a drive from a rotatable drive member. A mounting boss for supporting the mandrel so as to allow rotation of the mandrel while holding the mandrel against longitudinal movement, a coil support plate having one edge attached to the turns of the helical guide coil so as to support the helical guide coil along its length with the plate extending outwardly of the axis of the mandrel.

Coil winding machine

A device to produce a high capacity, low velocity, non-aspirating, semi-cylindrical air pattern, to be mounted in a ceiling. The device has a box-shaped backpan connected to a ceiling air duct and a flow directing assembly attached to the backpan and hanging below the ceiling. The flow directing component has a perforated face panel made up of flat surfaces in horizontal and angular planes, forming a substantially semi-cylindrical shape. Inside the face panel are four vanes that span its length, for controlling the direction of air flow. The flow directing assembly can swing away from the ceiling by a hinge along one side, or can be removed entirely using quick release means.
