General
The HLF

Linear Feeder is based on a balance of the oscillating forces by the prin-
ciple of opposing oscillation (push-pull). In order to ensure an effective balance of os-
cillating forces, it is necessary to keep the lines of action of the centres of gravity of
the working weight and counterweight as close together as possible. The position of
the centre of gravity of the counterweight is determined by the Linear Feeder design.
The centre of gravity of the working weight is determined by the construction design
specified for the working weight (e.g. feeder track). In order to ensure a good balance
of oscillating forces with minimum residual oscillation, the overall centre of gravity of
the working weight has to be located within the area specified in Table 2: Limiting co-
ordinates for the position of the centre of gravity of the working weight.

Mounting a linear track
The feeder track is attached by means of a side plate (see Figure 4). The side plate
is fixed precisely and reproducibly using fitting pins. Vertical slits in the side plate are
provided for feeder track attachment, allowing fine adjustment of the track entry and
exit interfaces in a vertical direction.
