Abstract

Device for vertically moving the trolley carrier of a trowel, which is of the type comprising a horizontal platform, switched at will merced to the corresponding driving engine and on which it is deposited, eventually with interchange of a pallet, the set of goods to enfarging through, generally, a band of film, mesh tissue or similar, of plastic material and that rolls helicoidally around these assembly, from a vertical feed coil mounted rotately on the carrier carrier, by the traction derived from the turnover of the quoted set of goods, in combination with the vertical and adjustable displacement of the coil, whose carrier carrier is mounted and guided in a vertical column of the boiler; characterized because it presents a relatively short spindle in relation to the height of the vertical column of the boiler, supported vertically and rotately in the said column and equipped with at least one nut, in which side is supported and rotately a first rolling axis of horizontal axis, whose first medium is hugged by a loop in "U" composed of two branches of a basically flexible linear medium, whose upper end is anchored in the column and that, after forming the quoted loop, conforms another loop in "U" inverted and that seated hugging a second rolling axis of horizontal axis, joining the lower extreme of the linear middle above to the carrier carrier, adopting in a joint single linear medium a path in "N" with its sensible vertical branches; because the extreme, preferably bottom, of the spindle is linked with the tree of a driving engine, parallel to such spindle, through a speeding variable medium, consisting of pulley paths, at least a variable diameter and fixed, respectively, to the spindle and motor tree and by a belt or similar that connects between themselves; and because the above motor is mounted into the column through a horizontally guide and sliding support, whose stable positioning is performed in the column through a horizontally guided and sliding support, whose stable positioning is made by an actionable medium at will that allows to vary the distance between the parallel shaft and the motor tree, producing automatically corresponding variations in the diameter of the respective pulley and altering, in a continuous and voluntary way, the relationship between its rotation speeds.
