the temperature of the hot plate 130 is sufficient to activate the adhesive and weld only the section x of the fabric to the width of the fusible tape 140 a folderjet 154 fig5 is provided just above the edge 120 of the plate 100 to assist in urging the section x of the fabric under the plate 100 air is directed to the air jet through conduit 156 and exist downwardly therefrom through a series of small openings not shown upon fusing of the interfacing liner tape 140 to the fabric section x the air regulator 152 is deactivated by the controller which permits roller 150 to move downward to the fig4 position thus permitting the hot plate 130 to drop downwardly slightly out of contact with the fabric section x prior to being retracted by the fluid cylinder 132 to prevent damage to the fabric and tape at the same time the controller actuates the cylinder 132 to withdraw the hot plate to the fig5 position motor 88 drives the belts 50 upon receiving a signal from the controller to advance the blank fused to the liner tape towards the sewing instrumentalities of the machine 32 when the forward edge of the advancing blank is detected by the sensor 160 fig1 the sewing instrumentalities are activated through the controller to hem the blank by stitching thus forming line 162 on pocket 24 after the pocket 24 leaves the sewing.
