Page 3: The New Generation Airbond Splicers - Background
We’ve done this by investing in cutting-edge new additive-manufacturing (3d printing) technology. From 2020 onward, all Airbond products will be printed, in materials which are more durable than those used in the past. The first generation of printed products will be familiar to our customers; they are direct replacements for the existing products - identical in shape and function.
Page 4: Model 701 Series 2; Summary
The range of application of the 701 Series 2 is just as remarkable as its predecessor. A unique and patented form of splicing chamber and splicing system is so powerful that a single specification can handle yarns of widely different counts.
Page 5: Changes To The Specifications
701 Series 2: Changes to the specifications In its original form, the Model 701 Splicer had an injection-moulded ABS body shell. Some fittings were made of metal, and were held in place by elements of the body shell, and screws. An example of this construction was the hanger wedge, which fitted into a recess in the body, and was secured by two screws.

Page 8 Model 701 – getting started Please read this section before you start operating the splicer. The rest of the manual deals with maintenance, and with details of products; those sections will not be needed immediately. Remove all packaging. For each splicer, you will have the appropriate splicing chamber – which will usually already be fitted.
Page 9: Splicer Threading
The Model 701 has been designed to splice low to heavy-count yarns in materials such as glass and carbon. Airbond research has shown that standard splicers – which typically make joints of around 30 mm in length – produce splices which are weak. Heavy-count yarns demand longer splices, typically up to 150 mm for 4800 tex.
Page 10 Now make the third. After the third splice, cut off the waste ends of yarn using a scissors. This technique has proved very successful with a number of materials; the picture below shows splices in glass, carbon and aramid. It is clear that the result for carbon is excellent –...
Page 11: Important Service Information
Important service information Apart from accidental damage, the Model 701 requires little attention. However, cleaning and specific lubrication should NEVER be neglected. Obviously, there should be frequent examination for signs of fibre build-up in the inner parts of the splicer. Fibre should be removed. Most important, the valve which actuates the chamber need lubrication.

Page 13 The 701 splices 4800 tex as routine, and in most circumstances it can handle 9600 tex. Now the Model 701 series 2 splicer is the direct counterpart to the Model 701 – similar in appearance but 3D printed in tough PA12 polyamide. Being 3d-printed, the Model 701 cases are made in one piece –...
Page 14 General description The Model 701 Splicer has a number of components mounted inside a case structure in which airways conduct the compressed air for the splicing action. Trigger - pressing the trigger initiates the splicing operation. Valve - operation of the trigger moves the valve allowing compressed air to pass into the body head for splicing.

Page 29 The body shells of the 701 Series 2 are held together by self-tapping screws, 4 x Items 1191 and 1 x Item 1194. Note that the screw (Item 1194) at the base of the handle is shorter than the others. Remove all of the screws to detach the upper case from the lower.

Page 31 Then release the feed tube from the upper compression fitting. This will permit the removal of the air union and feed tube. Lift away the trigger assembly, together with the chamber pad. Keep the assembly as one unit, unless you need to remove the chamber for maintenance or replacement.
Page 32 If required, press out the pad retaining pin, Item 1605, and separate the trigger Item 1614 and closure pad Item 1610 The closure pad mounting pin is an interference fit in the splicer trigger lever. This arrangement retains the closure pad, while allowing the pad to be a loose fit, so that it can align itself to the face of the splicing chamber..
Page 33 Lift the splicing unit out of the case, and detach the air feed tube, by compressing the quick-fit connector, and withdrawing the tube. Remove the splicing chamber. With a small tool, press the chamber securing pin, Item 1604, until it slides out. The chamber can then be removed from the Valve, Item 1606.
Page 34 To continue with complete strip-down: With the chamber removed, the compression washer can be seen; it is retained in place by two pins Item 1603. Using the same small tool as before, press out the pins, so that they come free from the main splicer body.

Page 37 Splicing unit: detail The splicing unit itself sits inside the outer moulding, so that it is not easily damaged in service. The entire splicing action is contained within the block shown in the photograph. The closure pad is at the top left. The splicing chamber is secured to a valve which runs inside the main splicer block.

Page 39: Compressed Air - Noise
Compressed air Pneumatic splicers are operated by compressed air. Therefore the air supply must be appropriate. The following points are important: Splicers generally operate at a pressure between 3 and 8 bar. Pressure may vary according to application, but it must be as uniform as possible. The air supply should be reasonably dry and clean, with the lowest possible flow resistance.
Page 40 Compressed air and safety All our splicers have been designed with safety in mind. The few moving parts have been enclosed or shielded to reduce the possibility of injury to the operator. In normal use, the only component which is in any way a source of hazard is the knife assembly.
Page 41 Compressed air and noise A splicer uses compressed air, which for a brief period - about 1 to 2 seconds – is vented to atmosphere while the splice is being made. Air at perhaps 7 bar pressure escapes through a small blast hole, creating intense turbulence in a small volume. Noise is inevitable.
Page 42: Troubleshooting
Troubleshooting Trouble with splicers generally takes one of two forms: poor splicing or component malfunctioning. 1) Splicing performance. If there is no apparent damage to the splicer, there may still be something subtle, which cannot easily be seen. It will be best, however, to look at the possible causes which are easy to spot. These include: Simple checks: •...
Page 43 Sticking valve Occasionally, the main valve in the splicing unit may stick. This could be the result of some form of damage to the internal components, but the explanation is normally much simpler; a lack of lubrication around the O-rings which seal the pad assembly, or an extension spring which has come adrift.
