ABSTRACT OF THE DISCLOSURE Coherent bands of suction tubes wrapped in individual protective envelopes are used to allow the mechanical and auto- matic application of suction tubes to individual packing con- tainers. The bands comprise two strips of flexible plastic material which are sealed to one another and between them en- close the suction tubes. To facilitate the separation of the suction tubes and surrounding protective envelopes from the band on application to the packing containers, the suction tube band is provided in accordance with the invention with transverse cuts between the suction tubes which at their ends lead into further cuts which extend in longitudinal direction of the band or have a selected length in -the said direction. The individual protective envelopes entering into the suction tube band are thus held together solely by two parts situated at a distance from one another and extending bandlike between the envelopes which can be cut through comparatively simply on application to the individual packing containers.
