Abstract: A process of manufacturing a hollow glass product with an offset collar axis, including the steps of inserting molten material into a cavity of a roughing mold, allowing the molten material to penetrate into a bottom portion of the roughing mold, perforating a collar by moving a punch into the bottom portion of the roughing mold along a non-vertical axis, extracting the punch from the bottom portion of the roughing mold, thereby completing processes of shaping the molten material into a blank, transferring the blank into a finishing mold by turning over the blank 180° with respect to a horizontal axis, and blowing the blank through the collar in the finishing mold such that the blank shapes into a hollow glass product. The cavity includes at least one input section which is substantially vertical.

Abstract: A process of shaping a hollow glass object, including the steps of roughing out molten glass into a rough mold with a collar and a shoulder, transferring the rough mold prepared in the roughing out step to a finishing mold, and partially driving the collar into the shoulder while maintaining at least one part of a height of the collar.

Abstract: A mold having a pivoting slide. The mold is made of two shells. An element is rotationally mounted on one of the shells with a part of the element coinciding with the internal cavity of the mold. The element is closed by the second shell which has bearing surface which acts on the element. The mold may be used for glassware products.
