The present invention relates to machines for wrapping
stacks of coins and other articles of ?at or cylindrical
con?gurations with one or several layers of a suitable
path and usually run between the rolls to the outside.
When such misdirection of the wrapping paper occurs,
the stack of coins will be rotated without being wrapped
in paper and the stack will fall apart after the pivotal
guide roller is withdrawn in a later stage of the operation.
There are known in the art wrapping units or assemblies
which cannot be adjusted and can hence be used only
for Wrapping coins of one denomination, or at least of
l0 coins which have substantially the same diameter. For
such non-adjustable wrapping units, the problem of reli

on one side and the following paper portion at approxi
mately one coin circumference between the tip of the
metal foil, etc. and also to machines for forming empty 15 paper and the wrapping roller behind it on the other side

Web Inserting Assembly
The web inserting or directing assembly comprises a
rotary upright shaft 80 to which is secured an inserting or
directing member 78 shown in the form of a blade of
considerably greater length than width.
The blade is
concavely curved in longitudinal direction as seen from
the wrapping roller 10 and may be tapered or wedge
shaped at its edge nearest to roller 10. Shaft 80 is sup
ported at its upper and lower ends by brackets 82 and 84
in whichit is rotatable. A spacer rod 90 is provided
at a small distance from shaft 80 parallel thereto. A
spring means 86 shown as a torsion spring is mounted on
shaft 80 and seeks to turn shaft 80 in clockwise direc
tion as seen in FIG. 6 into a position in which a limit pin
‘88 extending from shaft 80 abuts against a setsorew
threaded through rod 90. This screw is so set that blade
78 occupies approximately the position shown in 'FIGS. 1
movement of the arms is derived from and controlled by
the drive and control means 150. The cycle timer of the
control means is so set that during the transport of the
article to be wrapped into the wrapping position, cam
rollers 46 and 106 travel on the flat portion of camming
discs 48 and 108 which are rotated together with shaft 50.
Accordingly, all the parts of the machine other than the
components of the article feeding assembly remain in
the position of FIG. 1 and web feed rollers 52 and 54
do not rotate. The operation is so timed that when stack
76 reaches the position of FIG. 2, cam roller 46 begins
to ride upwardly on the slanted part of the carnming sur
face of cam disc 48. As a result, lever 40 is turned about
shaft ‘42 in clockwise direction against the action of spring
‘47 thereby causing rotation of lever 34 about shaft 24 in
counterclockwise direction. As a result, guide roller 14 is
pivoted from the position of FIG. 1 into the position of
FIG. 2 and while moving toward this position bends back
the web portion protruding beyond wrapping roller 12
into the position of FIG. 2. In the position of FIG. 2,
the stack is held between ‘the three rollers 10, 12 and
14 and the web is sandwiched between the peripheries
of the three rollers. Tip 112 is then located in the gap or
slot de?ned between stack 76 and the ?rst wrapping roller
10. The wrapping assembly is now closed.
The timing of the operation is such that cam roller 106
rides until the just described moment on the ?at part of
the camming surface of cam disc 108 also rotating with
shaft '50, but now begins to ride upwardly on the slanted
and 6. Brackets 82 and 84 are pivoted by means of
screws 93 and 95 to extensions 94 and 96 of levers 16
and 20. The free end of bracket 82 is pivoted by means
of a screw to a link 98 which in turn is pivotally connected
to a second link 100. Link 100 is ?xedly secured upon a
portion 105 of the camming surface. As a result, links 104 ,
shaft 102 which also ?xedly seats a cam follower lever
and 100 are turned in clockwise direction and link 98
104, the free end of which supports a follower roll 106.
This roll rides on the camming surface of a cam disc 108 50 turns lever 82 also in clockwise direction. Consequently,
blade 78 begins to move from the position of FIG. 1 past
which is ?xedly secured on shaft 50. A loaded tension

spring 110 urges roll 106 into engagement with the cam
