A machine for applying frames to fabric with the fabric accurately aligned with the frame. A work surface has blocks which are adjustable to position an outer frame along a line 45 DEG to the front of the machine. An air cylinder is supported over the work surface by an arm which is slidably adjustable relative to a column which is rotatably adjustable to position the air cylinder relative to the outer frame. A pressure plate of the air cylinder holds an inner frame to be pressed into the outer frame. A laser light source is supported by the column so as to be directed to any desired position on the work surface to align the fabric with the outer frame.
