- the transmission unit preferably comprises a first driving member and a second driving member, arranged to be rotated by at least one wheel, a first driven member and a second driven member.
- the coupling device is arranged to selectively actuate the first driven member or the second driven member, while a transformation device, configured to transform the rotary motion selectively transmitted to the first driven member or to the second driven member in the translational sliding motion of the reel-holder carriage.
- first driving member and the second driving member are made by means of toothed members, for example a pinion or a hub, keyed on a shaft integral with the axis of at least one wheel.
- the first driven member and the second driven member may be made by respective keyed idle pulleys on said shaft.
- the coupling device is preferably made by means of a fork member, selectively displaceable, along the aforementioned shaft, upon command of the control lever, to couple the first driven member on the first driving member or the second driven member on the second driving member.

- the apparatus 1 comprises a base 2 on which wheels 3, 4 are mounted to advance the apparatus itself, so that a winding material, for example a film of extendable material or tape, is wound around a specific product or a group of products.
- a winding material for example a film of extendable material or tape
- the base 2 is mounted on a pair of wheels 3 of larger diameter and on a pair of wheels 4 of smaller diameter, pivoting and idle, capable of directing the base 2 on a substantially circular trajectory around the product to be wound.
- the apparatus 1 also comprises a column 5 with a substantially vertical extension, fixed to the base 2.
- the column 5 has a sliding carriage 6 capable of housing a reel 7 for feeding the winding material.
- the apparatus 1 further comprises a push handle 8 for advancing manually the base 2 having the column 5.
- the handle 8 is associated with a control lever 9, for controlling the sliding motion of the carriage 6 along the column 5, as described in detail below.
- the apparatus 1 further comprises, according to the invention, a transmission unit 10 connected, preferably, to one of the wheels 3, 4 and configured to transmit the rotational motion of this wheel about the respective axis and transform it into a sliding motion of the carriage 6 along the column 5, in a controlled manner according to a rising or lowering direction.
- a transmission unit 10 connected, preferably, to one of the wheels 3, 4 and configured to transmit the rotational motion of this wheel about the respective axis and transform it into a sliding motion of the carriage 6 along the column 5, in a controlled manner according to a rising or lowering direction.
- the transmission unit 10 may comprise a first driving member, for example a pinion 12, connected to the axis 1 1 of the wheel 3 by means of, preferably, a flexible transmission means 13, for example of the chain type.
- the pinion 12 is keyed onto a shaft 14 on which a second driving member, for example a hub 15, is also keyed.
- the pinion 12 and the hub 15 have, preferably laterally, a set of teeth facing an operative portion, for example central, of the transmission unit 10 itself, for the activation of the aforementioned sliding motion of the carriage 6 along the column 5.
- the aforementioned operating portion of the transmission unit 10 preferably comprises a first driven member, for example a first pulley 16, and a second driven member, for example a second pulley 17, and a coupling device 18, for example made by a fork member interposed between the first pulley 16 and the second pulley 17.
- the first pulley 16 and the second pulley 17, which are idle and slidably mounted along the shaft 14, preferably have a respective coupling toothing, preferably arranged laterally, facing in each case the aforementioned coupling device 18.
- the first pulley 16 and the second pulley 17 each have a further toothing on a surface facing respectively the pinion 12 and the hub 15. Each toothing meshes with a corresponding toothing arranged on the pinion 12 and on the hub 15 to ensure the transmission of the rotary motion when the coupling device 18 is operated, as explained better below.
- the control lever 9 is provided for actuating the selective coupling of one of the pulleys 16, 17 and, respectively, the pinion 12 and the hub 15.
- control lever 9 is connected, by means of connecting members, for example by means of a metal wire, to the coupling device 18, in practice to the aforementioned coupling fork member, so that the sliding motion of the carriage 6 is selectively actuated.
- the selective actuation of the coupling device 18 therefore makes the pulley thus actuated integral with the respective transmission element, which in turn is integral with the rotation of the shaft 14, which may be operated in motion around its own axis by the rotation of the wheel 3 impacted by the advance of the apparatus 1 following the push of the operator on the handle 8.
- the pulleys 16, 17 are in turn connected to a transformation device 20, configured to transform the rotary motion transferred to one of the pulleys 16, 17 in a translational motion of the sliding of the carriage 6 along the column 5.
- the transformation device 20 comprises for example a first transmission pulley 21 and a second transmission pulley 22, around which a flexible transmission means 23, preferably of the belt type, may be wound to ensure that the rotational motion transmitted by means of the selective activation carried out by the coupling device 18 of the transmission unit 10 is transformed into a translational motion, having lifting or lowering direction corresponding to the aforementioned selective activation.
- the aforementioned flexible means 23 is wound around the first transmission pulley 21 , so as to present a first arm 24 and a second arm 25.
- the aforementioned arms 24, 25 are respectively wound around the first pulley 16, and the second pulley 17, in order to be coupled again around the second transmission pulley 22.
- the translational motion deriving from the rotary motion transmitted by the selective actuation of the first pulley 16 is opposite, in particular in the lifting direction of the carriage 6 (see in particular Figures 4a and 4b), with respect to the translational motion deriving from the selective activation of the second pulley 17 (see Figures 6a and 6b), resulting in a lowering motion of the same carriage 6.
- a reel 7 is arranged on the carriage 6 of the apparatus, ready to wind up a given product.
- the operator begins the winding cycle by fixing one end of the winding material around the product.
- the apparatus is then pushed by the operator, who holds the handle 8 for this purpose.
- the activation of the control lever 9 while the apparatus 1 is advancing causes the carriage 6 sliding on the column 5 to be lifted or lowered (see figures 4a, 4b, 4c, 7a, 7b, 7c and respectively 6a, 6b, 6c, 9a, 9b, 9c), thanks to the connection of the coupling device 18 with the transformation device 20.
- the transformation device 200 comprises a separate flexible means for each driven member of the transmission unit 100.
- the transformation device 200 comprises a first flexible member 210 and a second flexible member 220, for transmitting the motion, respectively, deriving from the selective actuation of the first driven member 160 and of the second driven member 170.
- first flexible member 210 and/or the second flexible member 220 are annular transmission elements, for example chains.
- the first flexible member 210 is therefore wound around the first driven member 160 and a respective pulley, not shown for simplicity in Figure 10.
- the second flexible member 220 is wound around the second driven member 170 and a respective further pulley, which is also not shown.
- a first arm 21 1 and a second arm 212 is defined for the first flexible member 210 from these windings, and a first arm 221 and a second arm 222 for the second flexible member 220.
- the carriage 60 holding the reel 7 is fastened to the aforementioned flexible members 210, 220, in a crosswise manner, to selectively activate the lifting or the lowering of the reel 7 along the column 5 (not shown in Figure 10 for simplicity). More precisely, the carriage 60 is fixed integral with a single arm of each flexible member 210, 220, chosen so as to ensure that the carriage 60 is integral with arms which, if actuated by the respective driven member 160, 170, are wound so that they move in the opposite direction.
- the carriage 60 is fixed to a portion of the second arm 212 of the first flexible member 210 and to a portion of the first arm 221 of the second flexible member 220.
- the first flexible member 210 transmits the motion received from the first driven member 160, causing, in the illustrated case, lifting of the carriage 60, due to the connection to the second arm 212.
- the second flexible member 220 thanks to the connection of the carriage 60 to the first arm 221 , may be dragged in the same lifting motion of the carriage 60, the second driven member 170 being idle on the shaft 140.
- the second flexible member 220 transmits the motion received from the second driven member 170, causing, again in the shown case, the carriage 60 to be lowered, thanks to the connection to the first arm 221 . Thanks to the connection of the carriage 60 to the second arm 212 of the first flexible member 210, this same member may be dragged, being arranged idle on the shaft 140, in the same descent motion of the carriage 60.
- the apparatus according to the invention in the different possible embodiments, therefore enables the spiral winding of a product with the only advancing movement of the apparatus itself on the wheels 3, 4.
