Abstract: An assembly apparatus and method for use in the manufacture of strain indicators of the type in which a window and an indicator area are provided in a fluid filled capsule. Movement of the indicator area with respect to the window gives a visual indication of the load condition of the indicator. The assembly apparatus comprises means to provide for the initial placement of the fluid filled capsule into the tensile member of the strain indicator. Thereafter a compressive force is exerted on the capsule in order to bring the indicator area of the capsule in close proximity to the window with the tensile element in a relaxed condition. Following initial assembly the apparatus of this invention exerts a tensile pull on the tensile member of the strain indicator which causes the indicator area of the capsule to be separated from the window. Gap measuring means are employed to measure the distance between the window and the indicator area with the tensile element in a state of tension.
