ABSTRACT OF THE DISCLOSURE An improved apparatus for conveying a strip of raw material for producing bags in a bag producing machine is disclosed which includes continuously operating conveyors, a inclined belt conveyor and intermittently operating conveyors. The inclined belt conveyor is disposed at the intermediate position between the upstream and downstream conveyors so as to displaceably hold the loosened part of the material strip on the inclined upper surface and includes an endless belt made of air permeable material such as cloth, net or the like. A suction device is arranged just beneath the endless belt of the inclined belt conveyor to suck air through the air permeable belt so that the strip is attracted toward the upper working surface of the inclined belt conveyor. To assure that the strip is delivered to the processing section in the bag producing machine, a horizontally extending guide roller is disposed above the inclined belt conveyer in the proximity of the latter at the working area extending between the middle part and the upstream end part of the inclined belt conveyor.
