Abstract: A device (1) equipped with pattern-controlled components (2) for pattern-controlled feeding and/or selection of yarn for a textile machine, comprising a plurality of actuators (4) and a cooling circuit (5, 8) through which coolant is flowable for the cooling of the actuators (4), whereby the actuators (4) in the device (1) are installed alongside the cooling circuit (5, 8) and are mountable so as to be detachable so that the actuators can be removed without interrupting the cooling circuit (5, 8). Furthermore, a textile machine comprising such a device (1).

Abstract: A device for cutting off weft yarn (27) during successive weaving cycles, comprising a cutting element (1) and a rotatable detaining element (2c), (13) which is forced to a detaining position by a spring force in order to detain the yarn and can rotate, under the influence of a tensile force exerted by a rapier on the detained yarn, counter to the spring force to a non-detaining position in which the yarn can be moved further towards the cutting element (1) in order to be cut. Such a device is efficient and can be made to be more reliable and more compact than existing devices. The invention also relates to a weaving loom provided with such a device.

Abstract: A giver rapier head (1) comprises a presentation space (9) between a successive guide nose (11), for leading off warp threads (23) on one side (7), and a selection nose (8), for leading off warp threads (23) on the other side, so that a weft thread (2) can be directly presented in this presentation space (9) and can engage from there in an insertion space (15) between the selection nose (8) and the first-mentioned side (7). A giver rapier (1) has a limit guide arc (10) which is arranged at the front side of the giver rapier (1) and a selection nose (8) which is arranged on the top side, with its top (26) facing the guide arc (10). A rapier weaving machine (20) comprises such a giver rapier head (1). In a method for inserting a weft thread (2), the giver rapier head (1) is moved towards this weft thread (2) while the reed (19) beats up an inserted weft thread (2).

Abstract: A frame (100) as subject of the present invention for positioning optical components (131, 210) of a projection device, is at least partially provided out of a polymer material. The frame has an outer surface, at least a part of this outer surface is a polymer outer surface (132, 133, 204, 205, 214, 215) provided out of a polymer material the frame is characterised in that at least a part of the polymer outer surface (132, 133, 204, 205, 214, 215) is provided with a deposited layer of UV-protection material for preventing UV-light emanating from said optical components (131, 210) from irradiating said polymer material.

Abstract: A convergence system 100 comprises a dichroic prism 102 for splitting and/or recombining light beams, intermediate parts 104a, 104b, 104c and a light modulator 106a, 106b, 106c for every color beam. The intermediate parts 104a, 104b, 104c are constructed such that the convergence system has an improved resistance for variations in environmental effects like temperature and humidity. The intermediate parts 104a, 104b, 104c are constructed such that the convergence system has a high stability, a large degree of monolithicy and a high movement isotropy. When used in a projection display system, the projection display system has a high degree of color uniformity.
