• An embodiment according to claim 12 can be the Envelopes approaching the conveyor level and still stacked with their leading edges in the direction of the passage gap slide to prevent twisting Envelopes have a tendency to jam.
• An embodiment according to claim 13 does not prevent only the bulging of what is captured by the drivers Envelope at its leading edge, but rather also an upward hump formation, since the Majority of the restraint paragraphs essentially the covers the front of the envelopes.
• An embodiment according to claim 14 ensures that the retaining heels are stacked with the level of the Envelopes match, even if the Stop surface of the stop delimiting the magazine in runs at an acute angle to this plane.
• An embodiment according to claim 15 allows Envelopes such a distribution that at each Restraint paragraph one of them is applied.
• Through the ge Staggered support is not just the supporting load rich in the longitudinal direction accordingly extended to the Bulging or buckling of what has been grasped for conveying Safe to prevent envelope, but find it already a multiple pre-isolation of the still stacked envelopes instead. This is a be particularly reliable separation when feeding the Envelopes to the office machine guaranteed.
• Of the gradually towards the lowest and last Retention surface moving envelopes is each only one to the last retention area and thus released for separation by the driver.
• Fig. 1 shows an upright stacking magazine 10 for holding envelopes 12.
• In fraud Device 14 is the stacking magazine 10 through a stop 16 limited by a stop surface 17.
• a conveyor belt 18 is arranged, the a first pulley 20 and a second pulley be 22 wraps around. To ensure that the För To ensure derriemens 18, this is called a toothed belt men trained.
• On the conveyor belt 18 is a take-away meryak 24 attached, which serves to each under first envelope on the removal side 28 from the Sta pelmagazin 10 to separate in the direction of arrow 14 and at for example the platen of an office machine unmit to be supplied directly.
• the driver tooth 24 engages on the down and directed in the conveying direction 14 folded part 26 of the below first envelope in order to pass it through a between the stop 16 and a base plate 52, 52 '(Fig. 2) To promote limited passage gap 30 (Fig. 1).
• the Passage gap 30 is for the passage of a single one Envelope 12 sized.
• the driver tooth 24 is for example riveted onto the conveyor belt 18. There with the rivet head 32 thus formed without interference the pulleys are running in these circumferentials Recesses 34 and 36 arranged.
• the Be condition that the length of the conveyor belt 18 is a multiple Ches of the circumference of the pulleys 20 and 22 is.
• the driver tooth 24 is sharp-edged and preferably formed undercut in the conveying direction in order to ver prevent the folding part 26 of the lowermost letter shock disengages from the driver tooth 24.
• the driver tooth 24 preferably consists of a harder one Material than the toothed belt 18 is produced.
• the device has two conveyor belts 18, and that all with the conveyor belt interacting elements in mirror pictorial arrangement on both sides of the stack maga interest 10 are available.
• the two mirror-image An Orders 44 and 46 are by means not shown to adjust to the width of the envelope changeable in their distance from each other. This is what it is for possible either both or only one of the mirrors pictorial arrangements 44, 46 relative to a spline shaft 48 to be slidable on the first two Pulleys 20 axially displaceable, but torsionally rigid are arranged.
• a with the splined shaft serves as the drive 48 connected but not shown gear, which, for example, with the platen of the office grandmother machine or drive-connected with an electric motor can be.
• FIG. 2 Which limit the stacking magazine 10 in the conveying direction 14 de stop 16 is shown in FIG. 2 in 16 and 16 'below Splits.
• One of the stacking magazine 10 on the removal side 28 delimiting bottom plate 52 is also shown in FIGS. 52 and 52 'divided.
