Abstract

912,327. Wrapping-machines. VERPACKUNGS-UND SCHOKOLADENMASCHINEN DRESDEN VEB. March 25, 1960, No. 10663/60. Class 94(1). A wrapping machine which is adjustable for articles of various sizes, feeds the articles by conveyer to beneath a folding shaft through which they are forced carrying a wrapper before them, and the folding shaft walls being adjustable for different article dimensions. Articles, such as books 23, fed from an adjustable magazine, Fig. 1 (not shown), are brought into alignment with the shaft and a plunger 16, by the conveyer 6. They then lie beneath a wrapper 27. The plunger thrusts the book and wrapper past folders 24, 24<SP>1</SP> which cause the wrapper to overlap beneath the book. Linked members 25, 25<SP>1</SP>, 26 (see especially Fig. 7) then advance horizontally, the members 25, 25<SP>1</SP> forming end tucks and the members 26 following the chain-dotted path in Fig. 4, to raise the book past members 29, 31, the latter being similar to the elements 24, 24<SP>1</SP>, which fold the wrapper end flaps 27 down and beneath the package. The package joins a stack which moves upwards until it contacts an adjustable feeler 41, Fig. 13. Raising of the feeler causes a cover member 47 to descend beneath the entrance level of an aperture 49 in a plate attached to a plunger 55. A pawl 48 on a reciprocating rod 51 may thus engage the aperture to advance the plunger and eject a stack of packages on to a shoot 42. The folders may include friction strips to assist tight wrapping.
