ABSTRACT:
This relates to a wrapping machine of the type wherein a web is automatically wrapped about one or a group of articles to form a package. A continuous web is provided and this web has at regular intervals a series of transversely aligned cutouts. After the web has passed over the article or articles to be wrapped, the web between two adjacent sets of articles is hooked onto a web drawing member of an article transporting conveyor which is moving at a greater rate than the article being wrapped. A simple web pressing mechanism is provided for pressing the web down in front of the web drawing member and holding the web portion in a pressed condition until the advancing web drawing member engages fingers thereof into the cutouts in the web. The web pressing mechanism is carried by an endless conveyor and is either fixed and the web drawing member is tilted by a cam to engage the web or the web pressing mechanism is actuated by a fixed cam so that the operation thereof is simple and the timing thereof with respect to the wrapping of an article remains constant and is assured.
