Embodiment Construction

[0041] exist figure 1 In , continuous filter rods 4 are supplied to the support surface 2 from a rod supplier 40, such as a rod forming device. A filter rod 4 , for example a PLA filter rod, is guided along the support surface 2 to the wrapping device 3 . In the wrapping device 3, a continuous filter rod 4 is wrapped with a piece of continuous wrapping material 5, such as wrapping paper. The support surface 2 may comprise a longitudinal groove 30 in the form of a half-circle for receiving the filter rod 4 and for supporting the wrapping material 5 around the filter rod 4 .

[0042] The wrapping material 5 is supplied from below the support surface 2 , for example from a spool, deflected by a deflection element 21 arranged upstream of the support surface 2 for transport on and along the support surface 2 into the wrapping device 3 .

[0043] The support surface 2 may comprise one or several rollers 20 which roll in the transport direction of the filter rod 4 and wrapping mate...

Abstract

The method for drying filter rods comprises the steps of providing a filter rod, providing a support surface (2) for receiving the filter rod (4) and guiding the filter rod on the support surface by aguide element (1) arranged above the support surface. The method further comprises the step of supplying a gas stream of compressed gas having a pressure between 0 and 6 bar to the filter rod throughthe guide element when the filter rod is transported along the support surface, before wrapping the filter rod with a wrapping material (5).

Description

technical field [0001] The invention relates to a method for drying filter rods. In particular, the invention relates to a method for drying a filter rod before wrapping it with a wrapping material. Background technique [0002] Typically, consumables used in electronic smoking devices are assembled from several segments. One of these segments may be a hollow acetic acid tube. Tubes were fabricated from endless hollow acetic acid rods wrapped in wrapping paper and cut to desired lengths. The wrapped and cut rods are stored in an intermediate manner before further processing, for example before being assembled with other segments to form consumables. Acetic acid material preparation may require steaming. Part of the vapor is still present in the rod material and also in the sections cut from the rod. This can lead to condensation of water in intermediate storage locations of the rod segments. Water condensation may adversely affect further processing of the segments. F...
