Secured; on, said. member adjacent the flange-is arr upstanding;bracket, a part of which overhangs but is-spaced above the as-' sociated 1 groove:v above mentionedQo This w =.bracket is providedabove said groove w-ithm a downwardly opening recess in lwhich a block like member "has-a vertically-guidedsliding, bearing and a part of'thisxblock V first; mentioned groove to complete'the firearswardly tapering, conical channel'of the folde12; Said block 'niembercarries' a guide'rod,

er which as shown herein includes a somea what rectangular plate member resting on i the base lofthe sewingmachine and having a depending flange 10at the frontby which said plate member is secured in place to the.
sewing machine baseby screws 11., About midway between-its ends there is provided onsaid plate inember,'an'upright flange 12 f that divides the plate inember into, what 7 may, lee-termed for convenience infutiire reference, as left and right handpartsor halves 1'3 andl respectively, 'theright'hand i part or half being of a lesser depthfrom front to real, than the left hand part.

relatively loose weave of the bagging. .q
Again, said original line of stitching is a not always straight and true so that these marginsare often irregular as to width'and theainount of fabric they contain. a c a In operating upon a bag for the resewing thereof, the operator brings that" marginal part'of the bagat its open en'd into position against the front-end of the flange 12 and ,;-moves "it rearwardly so "that said frayed margins are caused to enter the'channel 30,
{with the sidewalls ofth'ebag, passing under the lip 31 of the block'like member 22. This lifts theblock likeamember 22 against the action of the spring27 and in effect provides a slot that opens'laterally into said channel.
