PROBLEM TO BE SOLVED: To automate enclosing work of an exposed circuit part of a coil spring in a spring assembly for a mattress. SOLUTION: This enclosing machine apparatus of the exposed circuit part of the coil spring projected to one of upper and lower surfaces of the spring assembly, includes: a tractor 30 for drawing and towing non-woven fabric 22 applied to a support table 12 of a drum part 10; an elevator 15 constructed between the support table 12 and a fixed table 13 to control the liberation of the non-woven fabric 22; a front insert machine 40 for pushing in the non-woven fabric 22 to both side parts of the exposed circuit part; a bonding machine 50 for fixing the non-woven fabric 22 inserted in the exposed circuit part; a transfer machine 60 for moving the spring assembly 100 step by step; a cutter 70 for cutting the non-woven fabric 22; a support device 90 for setting the height of the spring assembly 100; and a control unit C to which a loading signal of the spring assembly 100 is input to output an actuating signal to a cylinder.
