A cable tie application tool is described that includes an electro-mechanical tensioning system. When the electro-mechanical tensioning system is controlled by a processor to tighten a cable, a reactionary force through a drive nut that is pivotally mounted to a tension bar can be monitored and measured by a strain gauge, a load cell, or other sensing system. This reactionary force is an indication of tension on the cable tie and is monitored by the processor until the tension reaches a predetermined tension, at which point, the processor causes a motor in the tensioning system to stop increasing the tension on the cable tie. The processor activates a cut-off system to cut the cable tie that has been tightened to the predetermined tension.

A fiber cutter includes: a base including a fiber grip that grips an optical fiber; a slider including a fiber end grip that grips an end portion of the optical fiber, wherein the slider moves relative to the base; a cut former including a blade forming an initial cut in the optical fiber and disposed between the fiber grip and the fiber end grip; and a spring that applies a force between the base and the slider to apply a tension to the optical fiber gripped by the fiber grip and the fiber end grip, wherein the cut former is disposed on the slide, and when the initial cut grows and the optical fiber cleaves, the cut former moves together with the slider by the force of the spring.

A method for film production includes the steps of obtaining information on the position of a defect (D) in a separator (12a) and providing marks (LA, LB) at the respective positions in the vicinity of the defect (D), the marks indicating the position of the defect.

A tool configured to tension an elongate cable tie around a wire cable bundle and sever a portion of a tie tail from the cable tie. This tool includes a pistol-shaped housing having a handle portion and a barrel portion. A slide mechanism disposed within the barrel portion comprises a gripper mechanism configured to grip a tail of the cable tie and a slide configured to move the gripper mechanism in a direction toward an end of the barrel portion and pull the tail of the cable tie through the tie head, thereby tightening the cable tie around the wire cable bundle. The tool also includes a tensioning mechanism that is configured to halt application of the tension to the cable tie when the tension applied by the slide mechanism reaches a predetermined tension threshold and a cutoff mechanism configured to sever the tie tail from the cable tie.

A chopper assembly for cutting filaments in a strand into short lengths, comprising two rolls (1,4) being rotatable in opposite directions and having a pinch where the rolls (1,4) contact each other. At least one of the rolls (1,4) is provided with cutting blades (2,5) at its cylindrical outer surface. Means (15) are present for guiding said strand to said pinch where the filaments of the strand are cut. Both axes of rotation (16,17) of the rolls (1,4) are parallel to the tangential plane through said pinch and make an angle (α) with each other, so that the cutting blades (2,5) move in axial direction with respect to each other in the pinch.

A cutting device for cutting an optical fiber running in a first direction includes a supporting piece having a free end and a fixed end and having resilience, a cutting blade supported by the supporting piece that comes into contact with the optical fiber to make a right angle with the optical fiber at a point of the contact, and a driving device. The driving device is configured to press the supporting piece in a second direction in a plane perpendicular to the first direction, with the second direction not intersecting with the first direction.
