Abstract

From a row of objects which are conveyed on an intermittently movable feeding conveyor, every second object is deposited on lines of wrapping materials at a first station, which lines are advanced continuously under the feeding conveyor, and the remaining objects are deposited on the same lines of wrapping materials at a following station. In connection with one or both depositing steps. the objects are shifted transversely of the direction in which said lines are advanced. Thus, the number of lines of wrapping material is only half the number of objects in each row, whereas the distance between the lines will be increased so much that the lines may be sealed lengthwise and crosswise by means of rotating sealing means. Two objects deposited one after the other on the same line at different stations are brought into exact position for the crosswise sealing by means of a pair of plates which are moved forwards and backwards over the lines in a cycle and which, during the forward movement, shift the objects forward on the line, the plates during their backward movement being lifted to clear the objects lying to the rear of the respective plates. The transverse sealing may be effected by means of a pair of rotating sealing blocks which are spring loaded individually.
