The invention is to provide a method for manufacturing a joined sheet product. The method comprising a first joining step including opposing a transverse end face of a first sheet product(1) to a transverse end face of a second sheet product(2) and joining release films of the first and second sheet products with a first joining member(30); a removing step including removing a portion of an intended member including at least a surface protecting member so as to leave at least the release film and a pressure-sensitive adhesive provided on the release film among the constituent members of both or any one of the first and second sheet products(1, 2), wherein the portion has a predetermined length from the transverse end face of the intended member; and a second joining step including providing a second joining member(40) on at least an exposed portion(40b) resulting from the removal of the intended member to join the surface protecting member sides of the first and second sheet products(1, 2).

A method is disclosed wherein a portion of a sensor part of an optical fiber sensor is embedded in an adhesive between two joined members, and peeling in an adhesive joint of the two members is detected on the basis of measuring optical characteristics from the optical fiber sensor when the optical fiber sensor is irradiated with light from a light source while one member is vibrated by vibration means. The method comprises the steps of determining the temperature of the two members during measurement on the basis of the optical characteristics from the sensor part exposed outside of the adhesive; determining, on the basis of the temperature determined during the measurement, the measurement range in which the optical characteristics from the optical fiber sensor are measured; and measuring the variation in the optical characteristics from the optical fiber sensor within the determined measurement range while the member is being vibrated by the vibration means.

The invention discloses a device for calibrating a plumb aligner. An upright column is provided with a plumb aligner holding cabin and an operating platform which are connected with a laser mirror cabin through a supporting column; the laser mirror cabin is connected with a fine adjusting cabin through a supporting column; the fine adjusting cabin is provided with a rough adjusting head; and the rough adjusting head is provided with a plurality of rough adjusting bolts. The invention provides the device and a method for calibrating the plumb aligner, which are used for calibrating a sight axis and a laser optical axis by taking a vertical axis and a zenith / nadir sighting mark (or remote fixed sighting mark) of the plumb aligner calibrated by a water level as dynamic bench marks. In the calibration process, the calibrated plumb aligner always keeps the leveling state during use, the target seeking task is completely finished by the zenith / nadir sighting mark, and therefore, the influence of included target seeking of the plumb aligner in the traditional method on the indeterminacy of a calibration result is greatly reduced. In addition, fewer adjustment times, shorter adjustment time, higher correction precision and more convenience for operation are realized.

The invention discloses a metal sheath stripping device for a rail transit cable. The device comprises a base, a fixed base plate, a stand column fixed between the base and the fixed base plate, a left motor support, a right motor support and two motors, wherein one of the two motors is mounted on the left motor support, the other motor is mounted on the right motor support, two sliding blocks are fixed on the lower surface of the left motor support in parallel, two sliding blocks are fixed on the lower surface of the right motor support in parallel, two linear guide rails are arranged on the fixed base plate in parallel and are embedded into grooves of the sliding blocks of the left motor support and grooves of the sliding blocks of the right motor support in sequence, a left baffle provided with an adjusting threaded hole is fixed on the outer side of the left motor support, a right baffle provided with an adjusting threaded hole is fixed on the outer side of the right motor support, a left connecting plate provided with a driving threaded hole is fixed on the outer side of the left baffle, a right connecting plate provided with a driving threaded hole is fixed on the outer side of the right baffle, the left connecting plate and the right connecting plate are located between the two linear guide rails, and the driving threaded holes are located below the left motor support and the right motor support. The metal sheath stripping device for the rail transit cable overcomes the difficulty in cutting and stripping of a metal sheath during detection, connection and installation of metal sheath cables, stripping efficiency is improved, and stripping of long metal sheaths is achieved.

The invention discloses an elevator cable stripping device which comprises a clamping mechanism and a stripping mechanism. The clamping mechanism is used for tightly clamping an elevator cable to be stripped. The stripping mechanism is used for stripping the elevator cable to be stripped. The stripping mechanism comprises a fixed tool set and a movable tool set, wherein the movable tool set can move in the axis direction of the elevator cable or in the direction perpendicular to the axis of the elevator cable. A channel for the elevator cable to pass through is arranged between the fixed tool set and the movable tool set. The fixed tool set and the movable tool set are respectively provided with a blade set with a tool edge matched with the elevator cable in shape. The invention further provides a stripping process using the elevator cable stripping device. The elevator cable stripping device and the stripping process enable an elevator cable sheath to be stripped quickly and accurately in an effort saving mode.
