## Background
BACKGROUND
In the industrial collection of maple sap used in the manufacture of syrup, it is not unusual for the manufacturer to have more than thousands of taps working at a predefined time. Where the topography allows, the main and branch lines leading to the manufacturing shed are organized to transport the collected sap to the shed via gravity. In another case, if the land is fairly flat in topography, then pumps must be used. According to the conditions, each taps is removably attached to the main line using a relatively short drop line.
As we discuss about the drop lines, if the maple sap is allowed to stay idle or stagnate in any one place for a short period of time, then it may become rancid within the main line and the drop lines. Therefore, tremendous amount of care is provided, even when the sap is running, to evade low regions in the sap lines where the sap might stagnate and ultimately get spoiled. Rancid sap confined in the lines can pollute running sap traversing through the effected regions and thus spoil a whole production bulk. Likewise, after the sap has been collected, the drop lines must be washed to maintain the assembly, and thus the drop lines must be removed periodically, or even changed. Since so many number of drop lines, for example, 1000 to 10,000 according to the size of the farmland area, there is difficulty in making this many number of drop lines, especially during an overall maintenance where all the drop lines have to be changed to put new drop lines. Conventionally, drop lines are changed every 3 years and most of the time the drop lines are made via single cutting tools, which a time is consuming process considering the number of drop lines required during a specific time.
Hence, there is a long felt but unresolved need for a cutting and insertion device which can cut elongate tubes into tube sections, which can attach the sap extraction fittings on the ends of the sliced tubes simultaneously along with the cutting process thereby reducing a reasonable amount of time in the manufacturing of such drop lines.

DETAILED DESCRIPTION OF THE INVENTION
FIG. 1A exemplarily illustrates a front perspective view of the cutting and insertion device 100, and FIG. 1B exemplarily illustrates an enlarged front perspective view of the cutting and insertion device 100 with respect to the portion marked A in FIG. 1A. The cutting and insertion device 100 disclosed herein for cutting an elongate tube 109 to tube sections 123, as shown in FIG. 2, comprises a frame section 101, a spinning wheel 102, a sheave section 103, a first pipe 104, a set of clamping members 107, and a set of plunger members 108. The spinning wheel 102 is fixedly attached the frame section 101 and is configured to mount a roll of the elongate tube 109. The sheave section 103 is fixedly attached to proximal to the end 101a of the frame section 101, where the sheave section 103 is configured to allow traversal of the elongate tube 109 through a first pipe 104. The first pipe 104 is fixedly attached adjacent to the sheave section 103, where the first pipe 104 is configured to receive the elongate tube 109, and comprises slits 105 proximal to opposing ends 104a and 104b of the first pipe 104 which are configured to receive a knife 106 hingedly connected to the frame section 101 to slice the elongate tube 109 exposed to the knife 106 at the slits 105 to form a tube section 123, as shown in FIG. 2. The knife 106 is, for example, a re-placable utility blade.
The clamping members 107 are fixedly attached to the frame section 100 and positioned proximal to the opposing ends 104a and 104b of the first pipe 104, where the clamping members 107 are configured to clamp the sliced tube sections 123 at opposing ends 123a and 123b, as shown in FIG. 2. The plunger members 108 are fixedly attached to the frame section 101 and positioned adjacent to the clamping members 107, where the plunger members 108 are configured to insert a fitting 110 to the plunger member 108 at the opposing ends 123a and 123b of the sliced tube sections 123, as shown in FIG. 2. After the cutting and insertion device 100 automatically calculates the predefined length of the elongate tube 109 required to be cut, the elongate tube 109 is allowed to traverse through the first tube 104. When the required length of the elongate tube 109 is received within the first tube 104, the plunger members 108 are actuated to perform two functions; firstly cutting the elongate tube 109 using the knives 106 operably attached to the plunger members 108, and then inserting the fitting 110 additionally attached to the plunger members 108 into the opposing ends of the sliced tube sections 123 as shown in FIG. 2. A tube section 123 inserted with fittings 110 into the opposing ends 123a and 123b of the tube section 123 forms the drop line 200, as shown in FIG. 2. Therefore, in a single actuation of the plunger members 108, both cutting of the elongate tube 109 and insertion of the fitting 110 into the sliced tube sections 123 is facilitated in the manufacturing of the drop line 200, as shown in FIG. 2, and therefore increases the speed of production of a large number of individual drop lines 200 within a specific time limit.
In an embodiment, the sheave section 103 comprises a driving pulley 111 and an idle pulley 112 configured to guide the elongate tube 109 towards the first tube 104.
