ABSTRACT:
A tufting machine feeds upholstered female and male button parts into drive mechanisms above and below a central table for receiving a cushion to be tufted. A retractable needle drive assembly forms an aperture through a cushion on the table along a drive axis of the machine, and, following retraction, a male button driver moves a male button part into the aperture and holds this button part on the drive axis while an upper drive mechanism drives a female button part onto the male button part to lock the parts together to complete a single tufting operation. Safety means prevent damage to elements and mechanisms of the tufting machine by possible malfunctioning or improper operation.
