Abstract

411,730. Wrapping-machines. TRIGGS, W. W., 57, Lincoln's Inn Fields, London- (Aktiebolaget Akerlund & Rausing ; 29, Kungsgatan, Stockholm.) Oct. 13, 1933, No. 28365. [Class 94 (i).] A machine for wrapping loaves and similar articles is mounted on a table 1, Figs. 1 and 6, and comprises a holder 3 for waxed wrappers, which are taken in turn by hand and placed over an opening 4, with one edge inserted under a clamp 5. The size of the opening can be varied by means of adjustable ends 7, to conform to loaves of different lengths. The height of the table 3 above the machine bed can be adjusted by means of screw supports 8, in sleeves 9, and adapted to be moved by nuts 10. A loaf a, Fig. 2, is placed upside down on the wrapper b, just over the opening, through which it is thrust with the wrapper. This folds the wrapper up round the loaf. A crosspiece 52 with a folding plate 53 is now moved to the right, Fig. 6, and forms the fold c, Fig. 4, and the operator turns down the folds d by an inward movement of the hands. A crosspiece 22 with uprights 56, 57 moves the packet to the right beneath a yielding member 15, which turns down the flap e upon the top of the loaf, the wrapper being released from the clamp by the movement of the packet. A heated plate 14 causes the over-lap to be sealed, adhesion being secured by means of yielding plates 12. The movements of the parts are derived from a driven shaft 31, on which is mounted a cam 30 engaged by a roller 28 on a lever 25. The lever is connected to a crosspiece 23 sliding on guides 20, which is automatically connected and disconnected to the crossheads 21, 22 in such a manner that the crosshead 21 is first moved from the position shown in Fig. 6 until it is adjacent to the crosshead 22. It is then disconnected and the crosshead 22 moves to the right, after which both parts are moved back to the positions shown. In order to compensate for the varying thickness of loaves, the plate 53 is set a little higher than is necessary, and an adjustable inclined surface 60 is arranged to engage a depending part 52 of the plate 53 so that the latter descends on to the loaf during its forward movement. In a modified form of machine, the folds d are automatically formed by swinging blades mounted on the part 52, or by sliding pieces which turn down the ends before the side fold is made. The bed on to which the loaf is pressed may be made yielding, and the folders may be in the form of rollers.
