A sewing machine comprises a base (1) with an area for receiving materials (28) to be sewn together, a hollow housing arranged on the base, a transporter (24, 30) for moving the materials during the stitching process, a sewing agent, and also a stitching and seaming mechanism comprising a device for conducting the sewing agent through the materials disposed in the sewing area. According to the present utility model, the sewing agent is a synthetic fluid mass that rapidly hardens in air and is housed in a container (3) arranged in the housing cavity. The device for conducting the sewing agent is in the form of a hollow cylinder (5) with spinnerets (8), which is mounted in the housing opposite the material receiving area in such a manner that the longitudinal axes of the spinnerets are oriented perpendicularly or at an acute angle to the surface of the materials to be sewn together. The cavity of the cylinder (5) is connected by a flexible tube (4) to the outlet of the fluid-mass container (3) and to a mechanism for changing the pressure in the cavity of the cylinder, and a controllable valve (10) is mounted upstream of the spinnerets (8), the valve being capable of passing or stopping a flow of fluid mass through the spinnerets (8) in synch with a change in pressure in the cylinder (5).
