The apparatus for wrapping compressible box-like articles (10) such as a stock of newspapers or magazines, with a web-like wrapping material (12). The apparatus has three serially arranged belt conveyors (16, 18, 20), and the second belt conveyor (18) is in the form of a bearing table (24) which can be rotated about a vertical axis (26). The bearing table mounts two pressure-exerting members (30, 32). The article (10') which is to be wrapped is introduced in a compressed state, by the first belt conveyor (16), into a wrap-around channel (42) which is formed by the table (24) and one of the pressure-exerting members (30), and the wrapping material (70) is positioned around the article in the form of a U. At the same time, the article (10), which has been previously wrapped in this way, is transferred to the third belt conveyor (20). A guide arrangement (62) for the wrapping material is then moved in a downward direction forming a loop of the material which is composed of a first end section (76) and a parallel second end section (78) which is guided along the trailing side (82) of the article. The loop of the material (70) is then severed at the base of the loop and the bearing table (24) is rotated in order that, as the article (10') is transferred to the third belt conveyor (20), the end section (78) is positioned against the article (10') to complete the wrapping. The first end section (76) is positioned to be engaged by the next article as it is advanced onto the table (24).

[ What is claimed is:] [13.]13. A method of wrapping compressible articles with a web-like wrapping material, comprising the steps ofwithdrawing a web-like wrapping material from a supply so as to form a free end section which extends downwardly across a predetermined conveying path of an article to be wrapped,conveying the article to be wrapped along said conveying path and into engagement with the free end section of the wrapping material, while compressing the article in a vertical direction by contact with one of two pressure exerting members which are spaced apart and positioned above respective opposite ends of a bearing table which is located immediately downstream of the free end section of the wrapping material, and such that the wrapping material is at least partially wrapped about three sides of the article and an end portion of the material overlies and extends beyond a trailing side of the article, thenrotating the bearing table and the article and the two pressure exerting members about a vertical axis, while maintaining the one pressure exerting member in compressive contact with the article, and thenconveying the article to a further position while causing the end portion of the material which extends beyond the trailing side of the article to overlie at least a portion of the bottom side of the article; andwherein a second one of the two pressure exerting members is adjusted in elevation to accommodate a next article to be wrapped prior to the rotation of the bearing table and the two pressure exerting members about the vertical axis being completed.
