Abstract: A tool capable of functioning in a first configuration as one type of cutter or pruner and in a second configuration as another type of cutter or pruner has functions to increase the comfort and efficiency of the cutting process. In some embodiments, a pruning saw assembly may be employed with the cutter mechanism for versatility.

Abstract: A layup machine for laying up and tacking sections of tape on a part to be produced, comprises: a first material drive/supply unit for supplying tape materials; first gripping means for drawing sections of tape from the first material drive/supply unit and for positioning the sections of tape in guide ways; a first cutter assembly for cutting to length the section of tape from the first material drive/supply unit; a motion table; and at least one tape tacking unit for placing on a tooling surface of a motion table and for tacking the sections of tape; characterized in that the layup machine furthermore comprises a second material drive/supply unit for supplying tape material; second gripping means for drawing sections of tape from the first material drive/supply unit and for positioning the sections of tape in guide ways; and a second cutter assembly for cutting to length the sections of tape from the first material drive/supply unit.

Abstract: A fiber placement machine has a fiber placement head and a K-axis housing that is supplied with fiber tow from a creel. The fiber placement head is mounted on the front of the K-axis housing. The fiber placement head has a compaction roller and a cut, clamp, and restart mechanism positioned adjacent to the compaction roller that receives fiber tow from the K-axis housing. A separable coupling connects the fiber placement head to the K-axis housing, whereby the fiber placement head may be disconnected from the K-axis housing for docking purposes.

Abstract: A system for applying composite fiber to a lay-up tool has a fixed creel for supplying fiber to the fiber placement dispensing head and a fixed arm having a first end attached to the creel and having a second end attached to the dispensing head. The dispensing head is fixed on the end of the arm. A robot having a first and second pivot axis and at least a first wrist supports the lay-up tool. The robot manipulates the tool for application of fiber from the head to the tool. Manipulating the tool instead of the dispensing head allows the path length for the fiber between the creel and head to be fixed in length and orientation during application of fiber to the tool.

Abstract: A fiber placement machine includes a movable wrist with a fiber placement head at one end of the wrist. A roller system for delivering fibers to the fiber placement head includes a J-axis roller located spaced from the ends of the wrist, a K-axis roller at the end of the wrist that supports the head, and an A-axis roller at the opposite end of the wrist. The axis of the K-axis rollers swivel depending on the rotation of the head, and the A-axis rollers swivel as a function of the swiveling of the K-axis rollers. As the A-axis rollers swivel, at least one end of the A-axis roller is displaced toward the J-axis roller to maintain a constant path length for the fiber tows between the A-axis roller and the J-axis roller.

Abstract: A fiber placement machine has a creel that supplies a fiber band to a presser member that applies the fiber band to a tool or form. The presser member is part of a head that is attached to the creel of the machine by a wrist that provides movement about yaw, pitch and roll axes with respect to the creel. The fiber band is supplied by a fiber band delivery system that is associated with the wrist and that is characterized by a capability to twist the fiber band in two stages about the yaw axis or the roll axis.

Abstract: Apparatus for applying uniform layers of adhesive to contoured surfaces of a substrate comprises, in one embodiment, a die head mounted to an adhesive dispenser and having contoured first and second die faces offset relative to each other. One of the die faces is operable to contact the contoured surface of the substrate, and a contoured slot outlet in fluid communication with the adhesive dispenser is disposed between the die faces for applying adhesive material to the contoured surface of the substrate. In another embodiment of the invention for simultaneously applying adhesive to multiple non-coplanar surfaces of a substrate, the die head comprises multiple non-coplanar die faces, each having first and second die face portions offset relative to each other. One of the die face portions of each multiple die face is operable to contact a respective non-coplanar surface of the substrate.

Abstract: A laser beam pathway is established through hollow robotic wrist elements, including plural elements rotatable around first and second wrist axes transverse to one another and intersecting at a junction point. The junction point lies within a mirror chamber formed within a base housing of the robot elements, and a mirror is mounted within the mirror chamber to assist in directing the laser beam. The beam passes collinearly with the first and second wrist axes and first and second ducts are provided with a rotary joint included in the second duct, to isolate the beam pathway from internal wrist drive elements.

Abstract: An articulatable robot has a forearm and robotic wrist, the wrist having plural members mounted on plural axes of rotation. A laser generator is connected through a light pipe system to the robot forearm, distal to the robotic wrist, and a continuous laser beam pathway is established through the forearm and robotic wrist, the beam pathway extending colinearly with the plural rotation axes of the wrist members.

Abstract: Plural rotatable elements are contained in a wrist assembly wherein at least two of the axes intersect at a junction point, and a continuous laser beam pathway is established through the wrist elements, the beam pathway extending colinearly with the first and second wrist axes, and a mirror is provided with a reflecting surface intercepting the junction point of the wrist axes to assist in directing the internally ducted laser beam.
