Abstract: A machine for producing bags includes a station for forming a tube, which forms a band of transversely perforated flexible material into a tube, a holding station for retaining the tube, a folding station for forming a bottom at the end of the tube, a folding roller having a folding blade for folding a flap at the end of the tube and a tear-off bar for pinching the tube against the drum, the folding station and the holding station being configured to jointly exert a traction on the tube and detach a portion of the tube. The tear-off bar is disposed behind the folding blade, the machine controlling the rotation of the folding station to synchronize the drum with the front of the tube.

Abstract: A method for sorting bags that includes filing past flat one after the other while being separated by a gap; the exterior edges of each bag are checked to determine whether a template and a position of the bag correspond to a calibrated bag or non-calibrated bag. The non-calibrated bags are ejected and the calibrated bags are presented in front of a visual inspection system to determine an acceptable or unacceptable quality of the inspected bag. The acceptable bags are stacked and the unacceptable bags are rejected after they have passed in front of the visual inspection system.

Abstract: According to a method for forming packs of flat bags, a continuous line of bags moving in an oriented direction of advance is received. The bags are moved onto a receiving table on which the bags are stacked while being stopped from moving in the oriented direction of advance by an abutment. The continuous line of bags is converted into a line of overlapped bags before stacking the latter, and the bags are separated on the receiving table by separating means comprising a separating device. During this operation, a separating device is inserted by a movement in the separating direction perpendicular to the plane of the bags between a preceding bag and a following bag in the overlapped line in such a way that, when the following bag stops against the abutment, it is supported at least partially by the separating means.

Abstract: Control device for activating/deactivating functions, comprising a supporting plate comprising a contact surface providing electrical contacts, a control member for selecting a function with the actuation of a switching means, the control member mounted rotatably about an axis of rotation and pivotably about a pivot axis separate from the axis of rotation, rotation and pivoting of the control member facilitating selection of a function and confirmation of the selected function. The control member may be associated with an actuating lever, of which one end comprises the axis of rotation, and of which the other end is mounted pivotably about the pivot axis, the lever being displaceable between a rest position and at least one active position in which at least one electrical switching means on the supporting plate is actuated for purposes of confirming a function, the axis of rotation and the pivot axis extending in separate extension planes.

Abstract: Control device for activating/deactivating functions, particularly of an automobile vehicle, comprising: a housing in which is produced a supporting plate comprising a contact surface, making electrical contacts, a control member selecting and confirming a function with the actuation of a switching means, the control member being mounted rotatably on an axis of rotation and pivotably about a pivot axis P separate from the axis of rotation R, rotation and pivoting of the control member facilitating selection of a function and confirmation of the selected function.
