themselves in a direction parallel to the direction of travel through the
machine. This direction is known as the "machine,"
"longitudinaI," or "with the grain" direction, and is at
right angles to the "across," "transverse" or

machine is one through which the packages flow from 1eft to right when the
machine is viewed from the front or normal operator location; on a
left-handed machine, the package travels from right to left.

a relatively high gloss; the reverse side is rough and not glossy.

transparent material and viewed through it, the image is the same as that on

The prominence of the line depends on the accuracy with which the mating
mould halves are matched. Also known as the mould parting line.
