## Abstract

A packing pocket for a device for inserting material into envelopes for sliding the envelope contents into an envelope. The packing pocket includes a mid-line (M) in relation to a transport direction of the envelope, as well as a number of slats which are parallel to the mid-line (M), and which are arranged on a plane (K) together with a flap guide. The slats are mounted on the device for inserting material into envelopes, on a mounting rail or on an adjustment rail. One or more slats are associated with a sheet guide arranged at a distance from the flap guide. In addition, the sheet guide is arranged in a spring-like manner in relation to the flap guide in a region of the packing pocket that is upstream of the envelope supply.

## Claims

### Claim 1

A packing pocket (9) for an inserting system (1), wherein the packing pocket (9) comprises:
a plurality of slats (28) extending in a direction parallel to a mid-line M, the mid-line M corresponding to a transport direction of envelopes, each slat (28) including a flap guide (13) extending in a plane K, wherein at least one of the slats (28) is configured to be mounted on the inserting system (1), on a mounting rail (15), on an adjustment rail (35), or at least on a mounting stop, and
a sheet guide (30) extending in a direction parallel to the mid-line M, wherein a first end of the sheet guide (30) is spaced from a first end of the plurality of slats (28) to define an opening for receiving envelope contents (5) and a second end of the sheet guide (3) is resiliently biased in contact with a distal end of the flap guide (13), characterized in that the at least one of the slats (28) configured to be mounted on the inserting system is designed to be mounted in such a way to the inserting system (1), that the at least one of the slats (28) does not have to be moved during an inserting operation, wherefore the first end of the sheet guide (30) is fixedly connected to the at least one of the slats (28), or to the mounting rail (15), or to the adjustment rail (35) or at least to one stop or to the inserting system (1).

### Claim 2 (depends on 1)

The packing pocket according to claim 1, characterized in that the biasing of the sheet guide (30) to the flap guide (13) is adjusted such that a speed of supply of envelope contents (5) is maintained for envelope contents of different thickness.

### Claim 3 (depends on 1)

The packing pocket according to a claim 1, characterized in that the sheet guide (30) is a spring.

### Claim 4 (depends on 1)

The packing pocket according to claim 1, characterized in that the sheet guide (30) extends at an angle relative to the flap guide (13).

### Claim 5 (depends on 1)

The packing pocket according to claim 1, characterized in that the second end of the sheet guide (30) touches an inner side of the flap guide (13) of the at least one of the slats (28).

### Claim 6 (depends on 1)

The packing pocket according to claim 1, characterized in that the packing pocket (9) comprises a spring which biases the second end of the sheet guide (30) toward the distal end of the flap guide (13).

### Claim 7 (depends on 1)

The packing pocket according to claim 1, characterized in that the slats (28) are mounted separately from one another and the packing pocket (9) has adjusting means (31) for displacing outer side slats (28′), which are on the outside relative to the mid-line M, in order to displace these in parallel to the mid-line M.

### Claim 8 (depends on 7)

The packing pocket according to claim 7, characterized in that the adjusting means (31) comprise electrical and/or mechanical means.

### Claim 9 (depends on 1)

The packing pocket according to claim 1, characterized in that at least one inner slat (28″) is arranged in a stationary manner between outer slats (28′).

### Claim 10 (depends on 1)

The packing pocket according to claim 1, characterized in that outer slats (28′) are at least partially closed on a respective outer side surface.

### Claim 11 (depends on 1)

The packing pocket according to claim 1, characterized in that outer slats (28′) form at least partially a U-shaped profile with an outwardly directed base, so that envelope contents (5) are guided on both sides of the packing pocket by the U-shaped profile.

### Claim 12 (depends on 1)

The packing pocket according to claim 1, characterized in that at least one inner slat (28″) is open on both side surfaces.

### Claim 13 (depends on 1)

The packing pocket according to claim 1, characterized in that the flap guide (13) is mounted on the inserting system (1), on a mounting rail (15) or on an adjustment rail (35).

### Claim 14 (depends on 1)

The packing pocket according to claim 1, characterized in that to at least outer slats (28′) a sheet guide (30) is assigned, which is at a distance from the flap guide (13).

### Claim 15 (depends on 1)

The packing pocket according to claim 1, characterized in that to at least one inner slat (28″) a sheet guide (30) is assigned, which is at a distance from the flap guide (13).

### Claim 16 (depends on 1)

The packing pocket according to claim 1, for an inserting system (1) for inserting the envelope contents (5) into an envelope (2), wherein the inserting system (1) comprises a holder (6) for empty envelopes, a flap opener (7) for opening an envelope flap (3) of the envelope (2), transport elements (8) for transporting the envelopes (2) from the holder (6) to the packing pocket (9) on which the envelopes (2) are filled, a supply device (10) for supplying the envelope contents (5) to the packing pocket and into the packing pocket (9), and onward transport elements (11) for the onward conveying of the filled envelope (2), and the inserting system (1) further comprises at least one of the following features: the mounting rail (15), the adjustment rail (35), the stop.

### Claim 17 (depends on 1)

A method for filling a packing pocket according to claim 1, wherein an envelope (2) with an open envelope flap (3) in front is transported to the packing pocket (9) and the envelope contents (5) are supplied to the packing pocket (9) by means of a supply device (10), wherein the envelope (2) is filled and then onward transport elements (11) convey the filled envelope onward, whereby the envelope contents (5) are guided into the packing pocket (9) wherein the envelope contents (5) are spring-biased toward the flap guide (13) by the sheet guide (30), at least in a front region in relation to the envelope supply, characterized in that the envelope contents (5) do not touch the envelope (3) until in the region of a front edge (53) of the packing pocket and the at least one of the slats (28) is not moved during the inserting operation.
