Method and device for strapping one or more packets with a band with label means
View Patent ↗A method and device for strapping one or more packets with a band, which device substantially comprises a frame, a lying conveyor belt supported by the frame for moving forward the packets, a pair of band clamping and guiding jaws movable toward and away from each other transversely of the conveyor belt, a supply reel associated with a jaw and guide members for the strapping band in addition to welding means co-acting with the jaws for welding together the band portions supplied by the pair of jaws, wherein means for arranging one or more label means at a time on the band are placed along the guide path of this band.
1. A device for strapping one or more packets with a band, comprising: a frame, a lying conveyor belt supported by the frame for moving forward the packets, a pair of band clamping and guiding jaws movable toward and away from each other transversely of the conveyor belt, a supply reel associated with a jaw and guide members for the strapping band in addition to welding means co-acting with the jaws for welding together the band portions supplied by the pair of jaws in a position substantially near the middle of the conveyor belt, a means placed along the guide path of the band for arranging one or more label means at a time on the band, and a means arranged for moving the band reciprocally to enable positioning of the band in front of the means for arranging one or more label means at a time on the band in a position offset from the position wherein the band is placed with the weld substantially near the middle of the conveyor belt.
2. The device as claimed in claim 1 , wherein the band is guided along a set of reversing rollers, and wherein the reversing rollers can be moved away from and toward each other to allow displacing and positioning of the band in a longitudinal direction.
3. A method for strapping one or more packets with a band and arranging label means on said band, which packets are ordered into a group, transported on a conveyor belt in a determined direction, a strapping band is tensioned transversely of this transporting direction wherein the band is placed with a new weld in a position substantially near the middle of the conveyor belt, this position offset from the position of arrangement of the label means, whereupon the band is moved reciprocally to enable positioning of the band, wherein first label means are arranged on the band and next the packets are pressed against this band, whereafter the band can be nestled around the group of packets, which band is welded together by means of heat, wherein label means are arranged beforehand on the band, and wherein label means are arranged on the band before the packets are pressed against the band.
4. The method as claimed in claim 3 , wherein prior to contact with the group of packets, the band is first moved in a longitudinal direction thereof in order to allow advance placing of the labelling position at a labelling station.
