Claim 3

A collating apparatus for the collection of sheets, comprising a frame, at least one series of adjacent trays positioned essentially horizontally in the frame, conveying means for conveying the sheets to be collated one by one along a path extending near the trays, guide elements associated with the trays which can be brought into the path of movement of the sheets to be collated, each guide element being movable between two positions, a first position wherein the guide element extends into the path of movement of the sheets for guiding sheets, and a second position wherein the guide element is situated out of the path of movement of the sheets, each guide element being activatable from the first to the second position by laying a sheet down into the corresponding tray with which the guide element is associated, the first position of each guide element being the only stable position of equilibrium, each guide element being provided with a flexible strip locking pawl with one end clamped relative to the frame, the second end resting freely on a horizontal part of the guide element in the first position of the guide element and cooperating in a detent clamping way with an essentially vertical part of the guide element in the second position of the guide element to positively lock the guide element in that position, and a common guide element activating means which upon activation brings all guide elements into the first position and releases the locking of the guide elements which are in the second position, the common actuating means comprising a vertical rod which is movable up and down in a parallel direction with respect to the frame, the rod being provided with a horizontal pin for each guide element flexible strip locking pawl which lifts the second end of such locking pawl during an upward movement of the rod and releases the same from the vertical part of the guide element.

Claim 4

A collating apparatus for the collection of sheets, comprising a frame, at least one series of adjacent trays positioned essentially horizontally in the frame, conveying means for conveying the sheets to be collated one by one along a path extending near the trays, guide elements associated with the trays which can be brought into the path of movement of the sheets to be collated, each guide element being movable between two positions, a first position wherein the guide element extends into the path of movement of the sheets for guiding sheets, and a second position wherein the guide element is situated out of the path of movement of the sheets, each guide element being activatable from the first to the second position by laying a sheet down into the corresponding tray with which the guide element is associated, the first position of each guide element being the only stable position of equilibrium, each guide element being provided with a flexible strip locking pawl with one end clamped relative to the frame, the second end resting freely on a horizontal part of the guide element in the first position of the guide element and cooperating in a detent clamping way with an essentially vertical part of the guide element in the second position of the guide element to positively lock the guide element in that position, and a common guide element activating means which upon activation brings all guide elements into the first position and releases the locking of the guide elements which are in the second position, the common actuating means comprising a vertical rod which is movable up and down in a parallel direction with respect to the frame, the rod being provided with a horizontal pin for each guide element flexible strip locking pawl which lifts the second end of such locking pawl during an upward movement of the rod and releases the same from the vertical part of the guide element.

Claim 5

A collating apparatus for the collation of sheets, comprising a frame, at least one series of adjacent trays located in the frame, conveying means for conveying the sheets to be collated one by one along a path extending near the trays, guide elements associated with the trays which can be brought into the path of movement of the sheets to be collated, each guide element being movable between two positions, a first position wherein the guide element extends into the path of movement of the sheets for guiding sheets, and a second position wherein the guide element is situated out of the path of movement of the sheets, each guide element being activatable from the first to the second position by laying a sheet down into the corresponding tray with which the guide element is associated, the first position of each guide element being the only stable position of equilibrium, and each guide element being provided with a locking element which, when the guide element has been brought to the second position, positively locks the guide element in that position.

Claim 6

A collating apparatus for the collation of sheets, comprising a frame, at least one series of adjacent trays located in the frame, conveying means for conveying the sheets to be collated one by one along a path extending near the trays, guide elements associated with the trays which can be brought into the path of movement of the sheets to be collated, each guide element being movable between two positions, a first position wherein the guide element extends into the path of movement of the sheets for guiding sheets, and a second position wherein the guide element is situated out of the path of movement of the sheets, each guide element being activatable from the first to the second position by laying a sheet down into the corresponding tray with which the guide element is associated, the first position of each guide element being the only stable position of equilibrium, and each guide element being provided with a locking element which, when the guide element has been brought to the second position, positively locks the guide element in that position.

Claim 7

A collating apparatus as claimed in claim 3, further comprising a common guide element activating means which upon activation brings all guide elements into the first position.

Claim 8

A collating apparatus as claimed in claim 4 wherein the activation of the common activating means releases the locking of the guide elements which are in the second position.

Claim 9

A collating apparatus as claimed in claim 5 wherein the trays are positioned essentially horizontally, the locking element comprises a pawl, a first end of which is movably connected with respect to the frame, and the second end of which rests freely on a horizontal part of the guide element in the first position of the guide element and cooperates in a detent clamping way with an essentially vertical part of the guide element in the second position of the guide element.

Claim 10

A collating apparatus as claimed in claim 6 wherein the locking element pawl comprises a flexible strip with one end clamped relative to the frame, the second end resting on a horizontal part of the guide element in the first position of the guide element and cooperating in a detent clamping way with an essentially vertical part of the guide element in the second position of the guide element.

Claim 11

A collating apparatus as claimed in claim 6 wherein the common actuating means comprises a vertical rod which is movable up and down in a parallel direction with respect to the frame, the rod being provided with a horizontal pin for each guide element locking element which lifts the second end of such locking element during an upward movement of the rod and releases same from the vertical part of the guide element.
