Abstract: A mask sewing device comprises a pair of sewing machines which are fixed to a working table, being arranged left and right thereon in such a way as to face each other, and are operated in synchronism with each other, a pair of belts provided apart from each other on the working table by a given interval, each belt extending between the mask cloth feeding side and mask cloth sending-out side of the working table and a feeding unit for driving the belts in the normal and reverse directions, wherein the sewing machines can concurrently sew the folded end portions of the mask cloth at both sides thereof respectively, the mask cloth being inserted into the interval from the feeding side.

Abstract: A drawing device for towel cloth for successively drawing out and cutting off a towel material of long size as long as a sheet of towel from the rest of the towel material at the plain woven portion thereof, the towel material of long size having plain woven portions and pile fabric portions alternately and continuously arranged at predetermined intervals in the longitudinal direction thereof. The drawing device comprises a feed roller disposed perpendicular to the drawing direction of the towel cloth on the drawing side thereof relative to the cutting unit and capable of feeding back the cut end portion of the cut towel cloth on the drawing side to the side of the towel material relative to the cutting unit and a thickness detector disposed in the same way as the feed roller orthogonally to the drawing direction of the towel cloth having an aperture-adjustable slit for stopping the pile fabric portion of the fed back towel cloth thereby.

Abstract: An automatic cloth feeding device in a cycle sewing machine is provided with first and a second cloth pressers which are placed on a working table and respectively hold and release both ends of the cloth in the lateral direction. Rotary motion of a first rotary shaft is changed to a linear motion by a first converting mechanism to cause the first cloth presser to move laterally while rotary motion of a second rotary shaft is changed to a linear motion by a second converting mechanism to cause the second cloth presser to move laterally. The first rotary shaft and the second rotary shaft are connected with or disconnected from each other by a clutch so that the first rotary shaft is driven by or released from a drive unit.

Abstract: A cloth presser mechanism comprises a cloth presser vertically movably supported by an arm of a sewing machine. A needle bar is vertically movably supported by the arm of the sewing machine and has a needle at the lower end thereof. The mechanism further includes a rack fixed to the needle bar, a pinion rotatably supported by the arm of the sewing machine and engaged with the rack, a cam integral with the pinion, a first link having an end pivotally supported by the arm of the sewing machine and a middle portion connected to a roller which rides on the surface of the cam, and a second link having an end pivotally supported by the cloth presser. The other end of the second link is pivotally connected to the other end of the first link.
