INTRODUCTION
The weft is guided in a controlled manner in every phase of weft insertion: from weft transfer to the projectile, through insertion into the shed, to beat-up. Worldwide, there are millions of projectiles in operation 24 hours a day The projectiles grip reliably a wide variety of threads, tapes or monofilaments and insert them in the shed. Reflecting the varying requirements for different weft yarns, projectile
grippers with various clamping forces and surface areas are available. One outstanding feature of projectile technology is that the weft is
inserted without central transfer, i.e. without additional acceleration and
braking. With this unique insertion technology, the P7300HP inserts all weft yarns in a controlled manner and with low yarn strain, thus helping to ensure maximum reliability in the production of quality fabrics.
The weaving machine for tomorrow’s needs
The versatility of the P7300HP is clear – in its equipment and in the many optional extras available. With accessories tailored to the application it can be customized to meet your exact needs. With the P7300HP you are investing in a future oriented, upgradeable weaving system. Thanks to its modular design, the machine can be adapted at low cost to meet new requirements. Thus it is a machine that can “grow” with your customers’ needs. Expanding the colour selector from two to four or even six weft colours is just as simple as switching from tappet
motion to dobby for shed formation
