Abstract
Abstract A method of and apparatus for forming a channel from a web of packaging material by passing the web over a body of substantially the desired cross section of channel and having guide edges, and changing the direction of movement of the web to form the desired channel. The goods to be packaged are supplied to the zone of the body in the direction in which the formed channel leaves the body.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
120 words
A method of forming an open channel from a folded cohesive web material in the shape of a semi-hose which is being fed from a supply reel for the continuous packaging of articles in channel sections divided off from said web material, comprising the steps of feeding said web material in a first feed direction to a stationary deflection zone; deflecting the cohesive web material in the shape of a semi-hose in said deflection zone thereby causing said semi-hose to open and form a channel and said web material to be fed in a second direction which is at angle with respect to said first direction; and feeding articles into said opened semi-hose forming a channel in said second direction.
Claim 2
Independent Claim
120 words
A method of forming an open channel from a folded cohesive web material in the shape of a semi-hose which is being fed from a supply reel for the continuous packaging of articles in channel sections divided off from said web material, comprising the steps of feeding said web material in a first feed direction to a stationary deflection zone; deflecting the cohesive web material in the shape of a semi-hose in said deflection zone thereby causing said semi-hose to open and form a channel and said web material to be fed in a second direction which is at angle with respect to said first direction; and feeding articles into said opened semi-hose forming a channel in said second direction.
Claim 3
Independent Claim
92 words
A device for wrapping articles comprising in combination, a supply reel of folded web materials operatively mounted in the device for feeding said folded web material in a first direction, a deflecting and shaping device operatively mounted in the device along the path of movement of said web material which is adapted to pass over it and be deflected into the second direcTion, said deflecting and shaping device having edge portions which form transversely with respect to the second direction a profile which corresponds substantially to the cross-sectional profile of said channel.
Claim 4
Independent Claim
92 words
A device for wrapping articles comprising in combination, a supply reel of folded web materials operatively mounted in the device for feeding said folded web material in a first direction, a deflecting and shaping device operatively mounted in the device along the path of movement of said web material which is adapted to pass over it and be deflected into the second direcTion, said deflecting and shaping device having edge portions which form transversely with respect to the second direction a profile which corresponds substantially to the cross-sectional profile of said channel.
Claim 5
Dependent Claim
27 words
A device as claimed in claim 2, in which one edge portion is horizontally disposed and in which the guide edge portions define an acute angle V.
Claim 6
Dependent Claim
24 words
A device as claimed in claim 2, in which the guide edge portions define a profiled opening which is bounded substantially on all sides.
Claim 7
Dependent Claim
17 words
A device as claimed in claim 4, in which the profiled opening has a substantially rectangular contour.
Claim 8
Dependent Claim
28 words
A device as claimed in claim 2, in which the guide edge portions have at least the major proportion of their overall length located in a common plane.
Claim 9
Dependent Claim
66 words
A device as claimed in claim 2, in which the shaping and deflecting device comprises two plate sections each of substantially triangular form and adjoining one another to include an acute angle, whose common joint edge defines the exit or advance direction of the channel and whose guide edges over which the web of material passes, recede obliquely in the exit direction, from the joint edge.
Claim 10
Dependent Claim
18 words
A device as claimed in claim 7, in which the angle included by the plate sections is adjustable.
Claim 11
Dependent Claim
28 words
A device as claimed in claim 2, in which the profiled body forms a groove or trough delimited by a horizontal transverse wall and side walls perpendicular thereto.
Claim 12
Dependent Claim
65 words
A device as claimed in claim 9, in which the groove comprises folding fingers disposed level with the top edges of the side walls and substantially horizontally, which in each case extend over part of the width of the groove and have their free ends, each of which extends beyond the vertical center line of the groove, located at different intervals above the base level.
Claim 13
Dependent Claim
19 words
A device as claimed in claim 2, in which the guide edge portions are provided with a friction-reducing coating.
Claim 14
Dependent Claim
33 words
A device as claimed in claim 2, in which the deflecting and shaping device consists of idler rollers over which the folded web material passes, the rollers defining a system of guide edges.
