摘要： A projectile accelerator has a coupling transmission articulated between a cam follower lever and a picking lever which has two end positions. The projectile accelerator also has an eccentric rocker on the drive shaft which cooperates with a tensioning lug on the accelerating shaft in order to carry out a return motion of the picking lever without need for a large angular movement of the cam follower lever. The picking lever is able to traverse large angles of movement while the cam following lever traverses reduced angles of movement.

摘要： A method of operating a catcher mechanism in a gripper projectile weaving machine and a catcher mechanism for performing the method are disclosed. The projectile ejection portion of the catcher mechanism is operated by opening the projectile yarn clip, ejecting the projectile from the picking path, closing the yarn clip and moving the members of the ejection mechanism out of the picking path by pivoting the members sufficiently to permit immediate entry of a following projectile prior to returning the ejection mechanism to the initial position.

摘要： The eccentric drive for lifting the heddle frame uses a mounting arrangement by which cam rollers can be detachably mounted on a cam-follower lever. The mounting arrangement uses a roller journal which is secured by bolts to the lever and which serves as a mount for a roller. The diameter of the journal surface on which the roller rotates is relatively large to provide a low surface pressure of the roller on the journal.

摘要： The torsion bar firing device is provided with a striking lever having an end piece at the distal end which acts directly on the abutment face of a projectile on firing. The striking face of the end piece of the striking lever and/or the abutment face of a projectile may be formed as inclined planes or as convex, concave, or concave-convex surfaces. The direct drive of the projectile by the striking lever reduces the masses to be accelerated and braked. This advantageously influences the energy consumption and the weaving efficiency of the projectile weaving loom. The end piece may be integral with the distal end of the striking lever or may be in the form of a rotatably mounted roller of a trapezium shaped element.

摘要： A picking mechanism for a loom including a projectile lift which points a projectile into a ready-to-pick position is made with a guide profile cross section open on the striking side. The projectile opener is provided with an additional guide element to guide the projectile body during movement into the ready-to-pick position. After positioning, the projectile opener with the guide element pivots away to expose a semi-circular space on the striking side of the projectile for the operation of a picking mechanism. The opener guide element may engage with an outer surface of the projectile during pivoting or may be positioned coaxially of a gripper opener to engage an internal surface in an additional passage in the projectile.

摘要： The coupling has at least one coupling part secured to the heddle frame with a toothed driving element extending from the beam into an opening in the drive lifter to engage with a second toothed coupling part. Each coupling part within a drive lifter is spaced from a wall of the drive lifter to define a passage to receive a driving element.

摘要： For the return of shuttles from the catching to picking side of a loom of gripper shuttle type, a housing encloses an endless belt and reaches from the catching to the picking side of the loom. Within the housing there is provided a separate guide rail for the shuttles, extending along one run of the belt. The rail is made of elastic material and includes one or more flanges for frictional engagement with the shuttles as propelled along the rail by carrying elements affixed to the belt.

摘要： The lubricant mist is supplied in timed fashion to at least one nozzle (31, 36, 40, 45) associated with a lubrication station in the zone of movement of a moving part (32, 37, 41 and 34 respectively). The timed supply of the mist is effected in dependence upon the position of a drive shaft from which the moving part derives its movement. The lubricant mist can therefore be supplied to the lubrication station in an accurately dosed quantity only when it is needed there. A possible use of the lubricating method is for looms where it is particularly important that the web of cloth produced on the loom should not be soiled by lubricant.

摘要： The picking mechanism is provided with two torsion bars. One torsion bar is stressed in order to accelerate a gripper projectile of the loom. The second torsion bar, upon release of the first torsion bar, is temporarily connected to the first torsion bar so that energy can be stored by the second torsion bar via a double-arm lever. During a return motion of the acceleration lever to a picking position, the second torsion bar is relieved of tension by delivering the stored energy to the drive shaft of the picking mechanism via the double arm lever. The picking mechanism thus uses only little energy.

摘要翻译： 采摘机构设有两个扭杆。 一个扭杆被压紧以加速织机的抓斗抛射体。 第二扭杆在释放第一扭杆时临时连接到第一扭杆，使得能量可以通过双臂杆由第二扭杆储存。 在加速杆返回到拾取位置的过程中，通过经由双臂杠杆将所存储的能量传送到拾取机构的驱动轴而使第二扭力杆释放张力。 因此，采摘机构仅使用很少的能量。
