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.

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.
