machine webs and other articles with warp and weft threads and which has a width more than 6 meters has a sley reciprocable in a direction of warp threads a thread introducing element formed as a projectile a shooting end catching mechanism for the projectile and guiding elements for guiding the projectile the guiding elements exclusively guide the projectile and are movable synchronously with the sley application_number US 21204094 A description fig1 for better understanding of differences between the full width power looms illustrates first a typical sley drive for shuttleless textile power looms a reed a and guiding teeth b are mounted together on a sley support c which extends over the whole width of the power loom the sley support c is fixedly connected with the multiple support d which in turn are all fixedly connected with a swinging shaft e the swinging shaft e and the elements a b c and d mounted on it perform an angle synchronous movement under the action of a cam disc drive f with a rotary point g and a two arm roller lever h which is also fixedly connected with the swinging shaft e this relatively low mass sley drive system due to the substantially high loads in the full width power looms and the considerable kinematic energies required here cannot be practically used for the sley impact a projectile power loom in accordance with the present invention shown in fig1 has a left outer frame wall 2 which supports a shooting mechanism 1 and a right outer frame wall 4 which supports a catching mechanism 3 a main drive 5 is located at the left machine side and a further main drive 6 is located at a right machine side between the housing walls 2 and 4.
