Model* from our range of cam type straightening and cutting machine* lake the wire from coil, straighten it by mean* of a rotating spinner straightener, feed and cut it into dose tolerance straight lengths.

Machines are available to cover a range of wire diameters from Q.3mm lo 19mm and all types of wire can be straightened from col producing perfectly straight lengths to dose tolerance with burr free cuts.

The wire is pulled from the coil through a five die spinner straightener by two carnages which alternately grip the wire and feed this through two tubular cut off dies. The required length is determined by setting the stroke and the number of strokes which the machine makes before the wire is cut, therefore any required length can be set. This type of machine does not require a run off section: the cut length* can be collected in either a stilleage or simple catching trough.

Single, two, three or four wires machines can be suppled — generally multiwire machines are available up to 5mm diameter wire, and single wire machines cover the range up to 19mm diameter. The nature of this machine makes it ideally suited for classes of wire which need lo be straightened without damaging the surface finish of the material, particularly plating quality, gold and silver and aluminium wire, as the wire is positively gripped by the tooling in the carnages there is no possibility of slip which would damage the wire. Marking is also reduced to a minimum in the spinner straightener and spinner dies can be supplied in different materials to suit the wire and correct selection will ensure that the surface of the Wire is not affected.

These machines are also suitable for straightening and cutting all forms of profile, flat wire and strip by replacing the spinner with a roller straightener.

As the wire stops momentarily to be cut. the nature of this machine makes it very suitable for the inclusion of secondary forming operations which can be carried out at the rest position; such forming operations include indentation, special cuts, and coining the wire to produce a coded stamp at each end of TIG welding electrodes.

Attachments can be supplied to form rings or segments on these machines — made m four versions, these attachments can be easily fitted to form accurate and flat rings, cutting these off radially and making the nngs suitable for butt welding.

For users which require an output of precise cut lengths, from reliable machines with little operator involvement, this range represents an ideal solution.

FEED This is effected by two cylindrical cams which provide both gnp and feed; as one carnage is gripping and feeding the wire, the other carnage is returning, the wire length is set by adjusting the two stops which limit the return stroke of each carnage and lengths are set by this stroke and the number of strokes which are made before the cut off mechanism engages

CUTOFF Two cylindrical hardened tool steel cut off dies give a good, square, burr free cut which does not damage the end of the wire. Tooling is included to cover four wire diameters and this is generally adequate to cover the whole range of the machine, however, additional cut off die* can be supplied where the quality of cut is vital. The cut off dies can be rotated and reground to give a good life. When the machine is being used for nng coiling, the cut is arranged after the last forming roll to ensure that no flats are produced on the ring. The cut is made by adjustable blades which can be positioned radially to the nng thus ensuring a square clean cut.

STROKE SETTING The standard form of setting the number of strokes is by fining pegs into a wormwheel which is dnven by the camshaft; the number of strokes has to be a number which devides equally into 24 or 48 depending on the model, As an alternative we can supply the machine with a counter which simplifies the method of stroke setting and any number of strokes can be set with this method. This also leads to a greater cut length output than the standard form and a comparison is included ; on the cut length output chart.

RING FORMING This is achieved by three honzonal (or vertical) rollers which revolve on needle race*. Two of these rolls are intended as guides, whilst the third roller forms the ring to the required diameter The rings can be produced flat by applying a minimum set to the spinner straightener and also by vertical adjustment on the rolls, Certain model* will produce continuous coil in addition to rings.

By simple modifications, all the machines in this leaflet can be made to handle strip or section material.

All machines are simple in design and easy to adjust, these can be run without an operator and will handle high carbon steel wire, copper and aluminium wire and plastic coated wire with suitable tooling.
