Abstract

Abstract In wrapping cylindrical goods or articles the article (1) is rotated about its axis, a stretch film (14) being wrapped round the article (1) substantially in a plane containing the axis of the article. A web-like wrapping material (24) is pressed against the cylindrical surface of the article (1) for rolling out on the article by rotation thereof. The stretch film (14) is wound over the material web (24). The stretch film can be one with a smooth and a sticky side, and which is pulled out from a supply (4). Winding the stretch film can be interrupted when the supply (4) is opposite one end surface of the article while the article rotation is continued a half turn, whereby the stretch film is laterally reversed in relation to the article. The film (14) can be initially wound with its smooth side in contact with the article (1) and later easily laterally reversed so that its smooth side is turned outwards to form the exterior of the article wrapping.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 81 words
A method in wrapping cylindrical article in a wrapping station, the article (1) being rotated about its axis and a stretch film (14) wound round the article, substantially in a plane containing the axis of the article, characterized by a web-like wrapping material (24) being placed against the cylindrical surface of the article (1) for rolling out against the article by the rotation thereof, and by the stretch film (14) being wound over the material web (24) on the article (1).
Claim 2
Independent Claim 81 words
A method in wrapping cylindrical article in a wrapping station, the article (1) being rotated about its axis and a stretch film (14) wound round the article, substantially in a plane containing the axis of the article, characterized by a web-like wrapping material (24) being placed against the cylindrical surface of the article (1) for rolling out against the article by the rotation thereof, and by the stretch film (14) being wound over the material web (24) on the article (1).
Claim 3
Dependent Claim 92 words
Method as claimed in claim 1, characterized in that the stretch film (14) is smooth on one side and sticky on the other and is drawn out from a supply (4), in that winding the stretch film is interrupted when the supply is in front of one end surface of the article (1), while the rotation of the article is continued a half turn so that the stretch film (14) is laterally reversed in relation to the article (1) and that winding the film is subsequently continued in the opposite winding direction.
Claim 4
Dependent Claim 50 words
Method as claimed in claim 1 or 2, characterized in that the material web (24) is delivered from a supply (25) displaceable parallel to the axis of the article (1) so that the winding pitch of the material web (24) on the article (1) may be given a desired pitch.
Claim 5
Dependent Claim 89 words
Apparatus for wrapping a cylindrical article (1) including means (2,3) for rotating the article (1) about its axis and means (4-7) for winding stretch film (14) about the article substantially in a plane containing the axis of the article (1), characterized by means (30-33) for carrying a supply (25) of a material web (24) in the vicinity of the surface of the article carried by the rotating means (2,3), and means (35,27,28) for applying the end of the material web (24) on the curved surface of the article (1).
Claim 6
Dependent Claim 89 words
Apparatus for wrapping a cylindrical article (1) including means (2,3) for rotating the article (1) about its axis and means (4-7) for winding stretch film (14) about the article substantially in a plane containing the axis of the article (1), characterized by means (30-33) for carrying a supply (25) of a material web (24) in the vicinity of the surface of the article carried by the rotating means (2,3), and means (35,27,28) for applying the end of the material web (24) on the curved surface of the article (1).
Claim 7
Dependent Claim 70 words
Apparatus as claimed in claim 4, characterized in that the winding means (4-7) is adapted for remaining stationary in a position opposite one end surface of the article (1) while the rotating means (2,3) rotates the article a half turn for allowing lateral reversal of the stretch film relative the article and that the winding means is adapted to wind the film in the opposite winding direction after said reversal.
Claim 8
Dependent Claim 34 words
Apparatus as claimed in claim 4 or 5, characterized in that the means (30-33) for carrying the material web supply (25) and the applying means (35,27,28) are adapted displaceable along the rotating means (2,3).
