models 501 and 505
The 400 Series splicers became well known in the textile industry, having a basic design philosophy which represented progressive development and improvement from the original 200 series of the mid-1970s.
The 400 series splicers had attributes which were proved in factories across the world:
- Rugged construction
- Quick to operate
- Wide range of applications
- Large capacity cutting knives
Later, customer response suggested that a splicer variant with superior yarn clamps should be supplied. In response to this feedback, the 500 Series was introduced, being offered alongside the 400 Series. Its yarn clamps were of superior design, and fully adjustable for compression and grip.
The Model 501 was the splicer of the series whose design was optimised for fairly small yarns, up to 3000 dtex, Nm 3.3. It was the direct equivalent of the 401. The splicer was generally used for continuous filament yarns
The Model 505 was essentially identical to the 501, except that its knives were more widely spaced, (32.5 mm compared to 30.0 mm). It was optimised for heavier yarns, from 2000 to 15000 dtex, Nm 0.6. It was the direct equivalent of the 405.
Since 2003, the 500 series has been superseded by the 1-11 Series. The 1-11 range, consisting of 18 variants, is simpler to operate than the 500 Series, has a simpler and more durable construction, and handles a wider range of yarns.
Although the 500 Series is no longer manufactured, it is still supported in part by a degree of after-sales service. The body can no longer be supplied as a spare part, but most of the small components remain available, either from stock, or to special order.
