pressing the adhesive strip about the stretch wrapping material.
I propose to deliver inside a wrapping machine getting roller means for rotating and supporting the cylindrical post being twisted, a carriage which can be movable longitudinally from the write-up to get covered and then in timed connection using its rotation. Manual means are given around the carriage for guiding and supporting the wrapping material over the cylindrical post. Means, for instance a cam means, is supplied for transforming the position of in clination from the information way to the cylindrical article to be able how the lead of your spiral wrap may be altered. Pace shifting path for changing the rate of longitudinal travel of your carriage are also supplied to ensure the speed of the carriage could then be different in primary amount for the modify from the position of desire of the manual indicates attached to the carriage. Signifies are offered for helping additional rolls of wrapping material in order how the comes to an end in the article to get twisted, that is to be considered a roll of document, could obtain reinforcing wrapping material. This strengthening material is applied as a right wrap, which is, one out of which there is absolutely no direct or angle of spiral.
In order to provide a protective layer of stretch wrapping material on the flat ends of the roll, Crimper means are provided on the machine at the opposite ends of oneof the rollers supporting the roll of paper so that part of the wrap overhanging the end of the roll of paper may be pressed or crimped inwards.
Given that moves of pieces of paper could effortlessly weigh up several tons,
ejector means are provided for ejecting the roll of document in the machine after it has been wrapped. Also provided is actually a tilting kitchen table so that the heavy roll of pieces of paper may be effortlessly put into the machine in the situation for wrapping. The invention will more evidently be understood by discussing the related sketches which demonstrate, through illustration, a machine for wrapping sizeable rolls of paper, and in the subsequent in depth information of the device. From the drawings:
1. In order to vary the lead of the helical wrap, speed changing means for varying the speed of longitudinal travel of said carriage in direct proportion to the change of said angle of inclination, and means interconnecting said cam means and said speed-changing means so that adjustment of one Will effect a simultaneous corresponding adjustment of the other, in a machine for helically wrapping cylindrical articles with a Webbed wrapping material roller means for supporting and rotating the cylindrical article to be wrapped, a carriage movable longitudinally of said cylindrical article and in timed relation with the rotation thereof, guide means on said carriage for guiding said webbed wrapping material over said cylindrical article, cam means on said carriage for changing the angle or inclination of said guide means to said cylindrical article.
