TEACHING AND E-LEARNING ABOUT DRAW FRAME MACHINE
TEACHING AND E-LEARNING ABOUT DRAW FRAME MACHINE

Summary/Abstract: This article presents a modern, e-learning method designed for the study of the draw frame for processing cotton fibers, blends of cotton and chemical fibers or chemical fibers cotton types. It exposes a new teaching and learning approach of the laboratory for subject Processes and Machines in Cotton Spinning Mill comprised in the academic curricula of the 3rd year students, specialization Technology and Design Textile Products and subject Processes in the Spinning Mill comprised in the academic curricula of the 2nd year students, specialization Economic Industrial Engineering. The draw frame is placed after the card machine or after the combing preparation system for combed yarns. The role of the draw frames is to increase the uniformity of the bands through the doubling effect of the bands, when a doubling of 6 or 8 is used and to increase the quality of the bands by straightening the fibers. The work is accomplished in PowerPoint aiming to capture the attention of the students. Besides, the transition from chapter to chapter or to additional relevant aspects within a chapter is carried out by means of hyperlinks. The kinematic and technological schemes developed in Autocad serve to calculus, kinematic and technological, and facilitate a better understanding of the functioning of the machine, part of the machine or different mechanisms. Supplementary, several images, audio and video files support the learning and understanding process. The video material derives from personal records or processing available movies in the public space, www.youtube.com, using Adobe Premiere Pro CS6 software. For each kinematic or technological parameter to be calculated, the respective kinematic chains are identified by changing the properties of the respective entities (kind, thickness or color of gears). The paper can be accessed from the official website of the university, http://www.uav.ro/, by accessing the platform on https://core.uav.ro/ containing all the bibliographic materials uploaded for university students. The access requires a username and password, both for teachers who publish information and for students as users.
