  • the removal takes place by means of the corresponding devices of the respective end cap stack, which contains the required end cap sizes and qualities, it must be ensured that only ever only a front cover is removed. Furthermore, the position of a single end cap stack in the staging area is arbitrary, so that the device for removing and handling the end cap, In particular, the manipulator requires a certain amount of time to locate the desired end cover within its effective range and to be adjusted in terms of its pivoting movements to this position of the end cover stack and the current stack height.

  • the device for receiving and positioning Due to the removal from a predefined removal area, it is also possible to make the device for receiving and positioning easier because the removal area can be made stationary and thus for each of the web rolls to be packaged, regardless of their dimensions, which determines the size of the end cover , is identical.
  • the device for receiving and positioning can thus be made much simpler and cheaper, since this is characterized by a nearly identical sequence of movements for all material web rolls to be packaged.
  • a calibration of the gripper of such a device for receiving and positioning end covers required from the prior art after the refilling of end cover stacks can be dispensed with. Due to the omission of the required storage of end caps stack only a corresponding means for cutting out end caps with the required parameters is required. The space requirement within the packing plant can be considerably minimized overall.

Due to the direct detachment from the packaging material, a part of the added value of the production of the end cover in the packaging process of the role itself can be integrated, since the packaging material can be purchased as a web goods considerably cheaper than finished cut, supplied end cover.
  • the separation from the packaging material web is carried out in a timely manner, depending on the requirement for the end face to be covered of the roll to be packed, that is, there are no front cover produced in stock, but in fact only depending on the upcoming packaging operations.
  • the removal area is maintained for all packaging operations, that is, is stationary or stationary, whereby the movement sequence of the device for receiving and positioning a single end cover can be considerably simplified and complex calibration processes can be omitted.
