The invention relates to a device for sealing-in pouring spouts in bags (1), comprising at least one station for opening (4) the bag (1), a station for inserting (4) the pouring spout into the opened bag (1), and at least one station for sealing (5, 6, 7) the bag (1) and the pouring spout. According to the invention, such a device is improved with a view to simple design and high processing speed in that the stations (2 8) for bag processing are arranged on a linear transport system (11) for the bags (1), which linear transport system (11) is formed by two transport belts (9, 10), and in that the stations (2 8) for bag processing are all arranged in a grid of equal spacing.
