Abstract: The present invention relates to a method for manufacturing non-slip socks, which arranges and presses a fabric to which a grapping member is bonded at the inside of the sock and then arranges and presses the fabric to which the grapping member is bonded at the outside of the sock. Here, accuracy of positions of the grapping members at the inside and the outside of the sock may increase by using a unit for guiding a position of the fabric, and productivity may improve. 
     A method for manufacturing non-slip socks, which arranges a gripping member (2) on a surface of a sock main body (1) fitted to a mold and presses and bonds the gripping member (2) to the surface of the sock main body (1) by using a press, the method comprising: 
     an inside setting process of preparing a mold (40) in which a fabric guide groove (43a), in which a fabric (3) onto which a grapping member is bonded is to be seated, is formed and then seating the fabric (3) in the fabric guide groove (43a), wherein the grapping member (2) faces upward; 
     a sock installation process of fitting the sock main body (1) to the mold (40) on which the fabric (3) is seated so that the grapping member (2) faces an inner circumferential surface of the sock main body (1); 
     an inside press process of preparing an one side press device (51) comprising a lower mold (50a) configured to support a lower portion of the mold (40), an upper mold (50b) spaced upward from the lower mold (50a), a heating wire (50c) installed in one of the lower mold (50a) and the upper mold (50b), and an actuator (50d) connected to the upper mold (50b), arranging one side of the mold (40) between the lower mold (50a) and the upper mold (50b), and then allowing the upper mold (50b) to move downward to heat and press the sock main body (1), so that the grapping member (2) at the inside of the sock main body (1) is bonded to the inside of the sock main body (1); 
     an outside setting process of preparing a guide device (60) comprising a movable frame (61) that moves upward toward the mold (40), wherein a fabric guide member (62) in which a guide hole (62a) configured to guide an arranged position of the fabric (3) on the sock main body (1) fitted to the mold (40) is formed is installed on the movable frame (61), and then arranging the fabric guide member (62) above the sock main body (1) and inputting another fabric (3) to which the grapping member (2) is bonded to the guide hole (62a), so that the grapping member (2) is disposed below the fabric (3); and 
     an outside press process of preparing a the other side press device (52) comprising a lower mold (50a) configured to support the lower portion of the mold (40) and an upper mold (50b) spaced upward from the lower mold (50a), comprising a heating wire (50c) installed therein, and connected with an actuator to vertically move, arranging one side of the mold (40) between the lower mold (50a) and the upper mold (50b), and then allowing the upper mold (50b) to move downward to heat and press the grapping member (2) on the sock main body (1), thereby bonding the grapping member (2) disposed on an outer surface of the sock main body (1) to the outer surface of the sock main body (1), 
     wherein the mold (40) comprises: 
     a connection plate (41); 
     a seat member (42) installed on the connection plate (41) and on which the fabric (3) to which the gripping member (2) is bonded is seated; and 
     an elevation member (43) in which a fabric guide groove (43a) through which the seat member (42) passes is formed therein and having a lower portion connected with the connection plate (41) through an elastic member (44) to vertically move by an upper pressure, so that the fabric (3) is not deviated from the fabric guide groove (43a) in a state in which the fabric (3) is inserted to the fabric guide groove (43a) after the inside setting process is finished.
