In order to carefully detach the cutting from the cutting table (1) without the web (17) remaining on the cutting table (1) it is proposed that the lifting device (14) which is provided at a distance above the cutting table (1) comprises a receiver which can be adjusted to the length of the boundary section (16) of the cutting (6) facing the raising device (4) and holds the received boundary section (16) in a transfer position lifted off from the cutting table (1) and the raising device (4) is displaceable between the lifting device (14) and the web (6) resting on the cutting table (1). ## Claims ### Claim 1 An apparatus for detaching a workpiece from a cutting table, which workpiece comprises a cutting cut out from a flexible web made of fiber material, comprising a raising device which is displaceable relative to the cutting table receiving the web with the cutting and which comprises a run-up surface for the workpiece ascending from the cutting table for progressively lifting the workpiece from the cutting table, a receiving device progressively receiving the workpiece after the run-up surface and a lifting device for the edge of the workpiece facing the raising device, wherein the lifting device (14) which is provided at a distance above the cutting table (1) comprises a receiver which can be adjusted to the length of the boundary section (16) of the cutting (6) facing the raising device (4) and holds the received boundary section (16) in a transfer position lifted off from the cutting table (1) and the raising device (4) is displaceable between the lifting device (14) and the web (5) resting on the cutting table (1). ### Claim 2 (depends on 1) An apparatus according to claim 1, wherein the receiving device (7) forms a support (12) which is stationary during the transfer of the cutting relative to the cutting table (1) and comprises a receiving surface (13) for the cutting (6) parallel to the table (1) on the bottom side facing the cutting table (1), and wherein the raising device (4) comprises a tape (10) which is deflected about the end of the raising device (4) facing the cutting (6) to be lifted and is guided along the run-up surface (8) rising up to the receiving surface (13) on the bottom side of the support (12), which tape is held in a stationary manner relative to the support (12) with its strand (22) running off the run-up surface (8) and clamps the cutting (6) between itself and the receiving surface (13) of the support (12). ### Claim 3 (depends on 2) An apparatus according to claim 2, wherein the tape (10) which can be applied with the help of the raising device (4) to the bottom side of the support (12) is arranged in an air-tight manner and the support (12) comprises a device for applying a negative pressure to its bottoms side. ### Claim 4 (depends on 2) An apparatus according to claim 2, wherein the tape (10) which can be applied with the help of the raising device (4) to the bottom side of the support (12) consists of a ferromagnetic material and the support (12) is arranged magnetically on its bottom side. ### Claim 5 (depends on 1) An apparatus according to claim 1, wherein the receiving device (7) forms a rest (33, 35) for the cutting (6), which rest is provided adjacent to the run-up surface (8) of the raising device (4) and is connected in a non-displaceable manner with the raising device (4), and the raising device (4) comprises a tape (10) which is deflected about the end of the raising device (4) facing the cutting (6) to be lifted, is guided along the ascending run-up surface (8) and is held with its strand (22) running off from the run-up surface (8) in a stationary manner against the cutting table (1). ### Claim 6 (depends on 5) An apparatus according to claim 5, wherein the rest (33) for the cutting (6) comprises a support (32) with a support surface for cutting (6) parallel to the table. ### Claim 7 (depends on 5) An apparatus according to claim 5, wherein the rest (35) for the cutting (6) is composed of individual support members (37) guided along a guide means (36), with the guide means (36) having a section (38) which is parallel to the table and a section (39) which is adjacent thereto and is guided back to the section (38) parallel to the table. ### Claim 8 (depends on 2) An apparatus according to claim 2, wherein the tape (10) receiving the cutting (6) is guided in an endless manner about deflections. ### Claim 9 (depends on 2) An apparatus according to claim 2, wherein the tape (10) receiving the cutting (6) can be wound off from a storage roll (9) associated with the raising device (4) and is held in a stationary manner against the cutting table (1) with its end (11) running off from the run-up surface (8). ### Claim 10 (depends on 1) An apparatus according to claim 1, wherein the receiving device (7) comprises a wound roll (43) for the cutting (6), which roll is held in a height-adjustable manner in a frame associated with the raising device (4) and rolls off with its roll on the cutting table (1). ### Claim 11 (depends on 10) An apparatus according to claim 10, wherein the guide means (44) of the wound roll (43) extends transversally to the incoming section of the cutting (6). ### Claim 12 (depends on 10) An apparatus according to claim 10, wherein the raising device (4) comprises a storage roll (9) for a tape (10) which is deflected about the end of the raising device (4) facing the cutting to be lifted, is guided along the ascending run-up surface (8) and is held in a stationary manner relative to the cutting table (1) with its strand (22) running off from the run-up surface (8) and is deposited in front of the wound roll (43) via a deflection device (45) as a roll support for the wound roll (43) on the cutting table (1). ### Claim 13 (depends on 1) An apparatus according to claim 1, wherein the receiver of the lifting device (14) comprises a lifting path rising from the boundary section (16) to be gripped towards the cutting (6). ### Claim 14 (depends on 1) An apparatus according to claim 1, wherein the lifting device (14) comprises individually triggerable lifting units (15) which comprise gripper elements (50) which grip underneath the cutting (6) from the side of the cutting gap (49) and clamping bodies (51) which cooperate with the gripper elements (50) and clamp the boundary section (16) of the cutting (6) between themselves and the gripper elements (50). ### Claim 15 (depends on 14) An apparatus according to claim 14, wherein the gripper elements (50) comprise gripper fingers (52) which are displaceable along a connecting link (53) and are flexible and ferromagnetic, and clamping bodies (51) which are provided with magnets.
