Machine for forming and wrapping up individual articles such as candies

Claim 1

A machine for forming and wrapping up individual articles with a so-called ''''tip or pin'''' type wrapping comprising: means for forming articles from a continuous plastic material web; an intermittently rotating radial section wheel for transferring said articles from a first stop station for successive sections to a second stop station for said sections; means for inserting said articles in said sections of said radial wheel at said first stop station; a transfer guideway extending from said second station and defined by two parallel facing surfaces; means for intermittently feeding successive lengths of wrapping material transversely intersecting said guideway; a wrapping wheel having a plurality of gripping pliers radially extending therefrom; means for intermittentily rotating said wrapping wheel; pusher means for transferring successive articles and related lengths of wrapping material engaged and urged by the respective articles along said guideway and between said surfaces from said second station to one of the gripping pliers of said intermittently rotating radial pliers so that each length of wrapping material along the guideway is substantially bent over in a U-shape about the respective article; and bending member means mounted adjacent said wrapping up wheel for bending the lengths of wrapping material for successive articles about said articles upon rotation of said wrapping wheel; and wherein said bending member means comprise a bending device which is fixed tangential to and surrounding the circular transfer path of the article to clinch one of the edges of the U-shaped length of wrapping material on the outer side of the article relative to said wrapping wheel; a substantially fork-like bending device, swingably straddling said pliers wheel for bending the end areas of a wrapping face against the heads of the articles perpendicular to said side; a fixed bending device substantially comprising two plates parallel to the faces of said pliers wheel and located adjacent and on either side thereof for bending over at right angles, in the manner of tips or pins parallel to one another, the wrapping ends during rotational movement of said pliers wheel; a bending surface guideway for clinching the end section of said edge on the next face of the article, thus terminating said tip or pin bending, and comprising a bending surface, gradually curving in the article feeding direction, for engaging said progressively bending over at least one of said tips or pins on the article; and ejector means for forwarding the successive articles from said pliers along said bending surface to the machine outlet.
