Method for fastening a paper product roll entity to a pallet and a paper product roll entity wrapped by plastic foil

Abstract

A method for fastening a paper product roll entity to a pallet by continuous plastic foil. The pallet has a cross direction and a longitudinal direction. A first sequence is repeated at least once. The first sequence includes wrapping the paper product roll entity such that a first continuous foil unwound from a foil head travels over the paper product roll entity and under the pallet, and moving in a cross direction a head of the foil or the pallet having the paper product roll entity on its substantially horizontal plane. After the first sequence, a second sequence is repeated at least once. The second sequence includes wrapping a second continuous foil spirally around the paper product roll entity.

(3) FIGS. 4 to 5 show a pallet and a paper product roll entity from above,

DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION

(6) FIGS. 1 to 3 show a pallet 2 and a paper product roll entity on the surface of the pallet 2 in a perspective view. The paper product roll entity may consist of a single roll 1, as shown in FIG. 1, or the paper product roll entity may comprise two or more rolls, as shown in FIG. 2. The rolls 1 may also be stacked, as shown in FIG. 3. The number of the stacked rolls can vary from two to several rolls. All of the above mentioned variables are possible, and further, any combination of those variables is feasible.

(7) Referring now to FIG. 1, the parts of the pallet will be described. The pallet 2 has a longitudinal direction L and a cross direction C. The pallet 2 comprises a horizontal plane 3 onto which the paper product roll entity is placed. Underneath the horizontal plane 3 there is a base 4. The base 4 comprises apertures 6 which extend in the longitudinal direction L of the pallet 2. The base also comprises passages 5 in which forks of a forklift can be pushed.

(8) FIGS. 4 and 5 show a pallet 2 and a paper product roll entity, in this case a roll 1, from above. The pallet 2 has been lifted up by forks 8 so that there is space for a foil head 9 to move under the pallet 2. The pallet 2 is transferred by the forks 8 so that one of the apertures 6 is at the foil head 9. The foil head 9 is adapted to circulate around the pallet 2 and the roll 1 along a circular loop so that the foil 7 travels via an aperture 6 and above the end of the roll 1 which is facing upwards. The foil 7 is made narrower when it passes the aperture 6 by inclining the foil head 9. It depends on the desired strength how many times the foil 7 is wound around the pallet 2 and the paper product roll entity. Typically, there are 4 to 6 layers on top of each other.

(9) After the adequate layers have been formed, the pallet 2 is transferred in the cross direction C so that the next aperture 6 is at the foil head 9 (see FIG. 5). The foil head 9 is adapted to circulate around the pallet 2 and the paper product roll entity in the same way as described above. The wrappingtransferring sequence is repeated as many times as desired. The number of times depends, for example, on the number of the apertures 6, but all the apertures 6 are not necessarily used. On the other hand, it is possible that the pallet 2 is transferred back and forth when the number of the repeated sequences is greater that the number of the apertures 6.

(10) FIG. 6 shows a side-view of the pallet 2 and the roll 1 after the first sequence at the first wrapping station. The foil 7 covers at least partially the end of the roll 1 which faces upwards and is wound around the pallet 2 via the apertures 6. The forks 8 remain inside the ring which is formed of the foil 7. In the end of the first sequence the foil 7 is cut off.

(11) After the first sequence at the first wrapping station has been finished, the pallet 2 is released from the forks 8 to the conveyor, and the pallet 2 and the roll 1 are conveyed to the second wrapping station. The second sequence is accomplished at the second wrapping station.

(12) A foil head 10 is adapted to travel spirally around the pallet 2 and the roll 1. The second sequence typically starts from under but it is also possible that the second sequence starts from above. Further, the foil 11 may form several spirally wrapped layers. The foil 11 tightens the foil 7 so that the roll 1 is fastened firmly to the pallet 2. The tightening effect of the foil 11 can be seen from FIGS. 6 and 7. In FIG. 6, the foil 7 is straight but in FIG. 7 it is curved. The method shown in FIGS. 6 and 7 can also be applied to such a roll or rolls which lie on the horizontal plane of the pallet 2.

(13) After the foil 11 has been wrapped adequately around the roll 1 and the foil 7, the foil 11 is cut. Thus, the package of the roll 1 is ready.

(14) FIG. 8 show a pallet 2 and a paper product roll entity on the surface of the pallet 2 in a perspective view. In this case, the paper product roll entity is a single roll 1 which lies on the surface of the pallet 2. It is also possible that two or more rolls 1 lie on the surface of the pallet 2.
