Abstract
In a machine for wrapping articles such as cigarette packets, feed rolls deliver a wrapper web onto a suction drum at a controlled speed which is less than the peripheral speed of the drum. The drum carries a cutter blade which cooperates with a fixed blade to sever successive leading sections of the web which are conveyed from the drum by a delivery conveyor moving at the same speed as the drum. Eccentric pinch rollers momentarily grip each wrapper section to assist separation from the web. The delivery conveyor transfers the wrapper sections to a further conveyor which conveys successive sections across the path of articles to be wrapped. The further conveyor has a lower run for diverting the leading portion of each wrapper section away from the article conveyor.
Claims16
A wrapping machine comprising means for feeding a wrapper web at a first speed, a suction conveyor for receiving the web from the feeding means, means for driving the suction conveyor at a second speed which is greater than said first speed, severing means including a first element carried by said suction conveyor and a second element which cooperates with said first element to sever the web into wrapper sections at a predetermined position of said first element, and delivery conveyor means for receiving said severed wrapper sections from the suction conveyor and for conveying them towards a position at which articles are wrapped, said delivery conveyor means including cyclically-operated means synchronised with said severing means for assisting separation of successive wrapper sections from the web after severing by exerting a cyclic pulling force on said wrapper sections.
A wrapping machine comprising means for feeding wrapper sections on a first path, means for conveying articles to be wrapped on a second path which intercepts said first path at a wrapping position so that an article moving on said second path intercepts a wrapper section on said first path and becomes partially enveloped in it, and guide means for successive leading portions of said wrapper sections on said first path downstream of said wrapping position and arranged to divert said portions from the path of said article conveying means, wherein said guide means comprises conveyor means having a first straight portion extending up to said wrapping position and a second straight portion downstream of said wrapping position, said second portion being inclined relative to said first portion.
A wrapping machine comprising means for feeding a wrapper web at a first speed, a suction conveyor for receiving the web from the feeding means, means for driving the suction conveyor at a second speed which is greater than said first speed, severing means including a first element carried by said suction conveyor and a second element which cooperates with said first element to sever the web at a predetermined position of said first element, and endless delivery conveyor means for receiving severed wrapper sections from the suction conveyor and for conveying them towards a position at which articles are wrapped, said delivery conveyor means including means defining a substantially straight path for receiving wrapper sections directly from said suction conveyor.
