Abstract
A method and apparatus of labeling cylindrical articles feeds labels onto a label drum. The labels have a formed curl such that the leading edge tends to curl away from the surface of the label drum. The article is fed onto the label drum and wrapped by engaging the article with the leading edge of the label and then wrapping the article. An uncut label web can be fed over an edge to impart the desired curl to the label web. The label web is then cut into labels, which are fed onto the label drum. Also, the tension of the label over the edge can be varied so as to vary the amount of curl imparted to the label.
Claims45
A method of labeling cylindrical articles comprising the steps of
- feeding labels onto a label drum, wherein the labels have a formed curl such that the leading edge tends to curl away from the surface of the label drum, and
- feeding an article onto the label drum and wrapping the article with the label by engaging the article with the leading edge of the label and then wrapping the article.
A method of labeling articles comprising the steps of
- feeding labels onto a label drum, wherein the labels have a formed curl such that the leading edge tends to curl away from the surface of the label drum, and wherein the label defines leading and trailing edges, and a medial portion between the leading and trailing edges, and wherein at least the leading edge and medial portion of the label are devoid of adhesive.
- feeding an article onto the label drum and wrapping the article with the label by engaging the article with the leading edge of the label and then wrapping the article.
An apparatus for labeling cylindrical articles comprising
- a rotatable label drum,
- means for feeding labels onto the surface of the label drum, wherein the labels have a formed curl such that the leading edge tends to curl away from the surface of the label drum, and
- means for feeding an article onto the label drum and engaging the article with the leading edge of the label for wrapping of the article.
An apparatus for labeling cylindrical articles comprising
- a rotatable label drum,
- means for feeding labels onto the surface of the label drum, wherein the labels have a formed curl such that the leading edge tends to curl away from the surface of the label drum, and wherein the labels have leading and trailing edges, and a medial portion defined between leading and trailing edges, and wherein at least the leading edge and the medial portion of the label are devoid of adhesive, and
- means for feeding an article onto the label drum and engaging the article with the leading edge of the label for wrapping of the article.
A method for labeling articles comprising the steps of
- feeding labels onto a label drum, wherein the labels have a formed curl such that the leading edge tends to curl away from the surface of the label drum,
- feeding an article to be labeled into a label applying position,
- blowing air from a first position on the label drum onto the leading edge of the label at an angle to the label drum surface and in a direction backward along the label from the leading edge to force the leading edge of the label against the article,
- after the leading edge of the label has engaged the article, blowing air from a second position on the label drum spaced from the first position and onto the label and article at an angle to the label drum surface to maintain a laminar flow of air against the label and maintain the label tight against the article during article rotation, and
- maintaining the leading edge of the label against the article while rotating the article so that the label is fully wrapped about the article.
An apparatus for labeling articles comprising
- a label drum having a surface on which labels having leading and trailing edges are retained, and rotatable for moving labels into a label applying position,
- means for feeding labels on the surface of the label drum, wherein the labels have a formed curl such that the leading edge tends to curl away from the surface of the label drum.
- an article feed for feeding an article into the label applying position,
- means for blowing air outward from a first position on the label drum onto the leading edge of the label at an angle to the label drum surface and in a direction backward along the label from the leading edge to force the leading edge of the label against the article,
- means for blowing air after the leading edge has engaged the article from a second position on the label drum spaced from the first position onto the label and article at an angle to the label drum surface to maintain a laminar flow of air against the label and help keep the label tight against the article during article rotation, and
- means for maintaining the leading edge of the label against the article while rotating the article so that label is fully wrapped about the article.
