Abstract
The invention teaches an environmentally friendly straw and its manufacturing method. The straw includes a tubular body having a through channel inside connecting two openings respectively at two ends of the tubular body, an outer layer surrounding the tubular body between the two openings formed by a leveling machine, an inner layer, as an inner wall of the tubular body, surrounding the channel formed by a honing machine. The straw is manufactured by leveling the tubular body, and honing the channel by a honing machine. As such, a smooth layer between the channel and the tubular body is achieved so that the straw is convenient to clean and use.

An environmentally friendly straw, comprising:
- a tubular body having a through channel inside connecting two openings respectively at two ends of the tubular body;
- an outer layer surrounding the tubular body between the two openings, where the outer layer is formed by a leveling machine;
- an inner layer, as an inner wall of the tubular body, surrounding the channel, where the inner layer is formed by a honing machine;
- wherein the honing machine comprises a honing driving member, a rotational member, and at least an abrasive element;
- the rotational member is joined to and engaged by the honing driving member to spin;
- the abrasive element is configured around the rotational member;
- and the tubular body is reciprocally worked by the abrasive element.
A method of manufacturing an environmentally friendly straw, comprising the steps of:
- (a) providing a tubular body, where the tubular body has a channel inside connecting two openings at two ends of the tubular body, respectively;
- (b) placing the tubular body on a leveling machine, where the tubular body is supported by a plurality of support elements of the leveling machine contacting the openings, respectively;
- (c) leveling the tubular body by a leveling element driven by a leveling driving member of the leveling machine against the tubular body, where a straightness of the tubular body is measured by a straightness measurement member of the leveling machine;
- (d) placing the tubular body after leveling by the leveling machine on a honing machine;
- (e) configuring at least an abrasive element on a rotational member of the honing machine;
- (f) spinning the abrasive element by the rotational member rotated by a honing driving member of the honing machine;
- (g) threading the abrasive element into the channel through the openings;
- (h) moving the abrasive element reciprocally inside the channel;
- and
- (i) forming an inner layer around the channel inside the tubular body by the abrasive element's reciprocal movement.
