To secure a button 17, Fig. 3, held in the rotatable knotter, and button 18 held with presser foot 15, on either side of padded article 16, needle 19 carries thread through the buttons, and hook 20 is rotated to secure button 18 as shown in Fig. 6. The rotatable knotter comprises pivotable button holding jaws 12, Fig. 1, arcuate wall 10 having shoulder 11 and open-ended slot 12, cam 13 and ejector 14. When the knotting means is rotated clockwise, Fig. 9, shoulder 11 forms thread loop 22 about wall 10 which thread portions 23 pass along slot 12 and are projected partially through loop 22 by cam 13. Hook 24, Fig. 10, then hooks the projecting part and draws portions 23 through the loop. The thread is then severed between the knotting means and needle, and the free end drawn through the loop to form the knot. Ejector 14 is moved to disengage the loop from shoulder 11.
