A spool for sewing thread comprises flanged end pieces (1, 5), made of plastics material, and either a single sleeve (2), or inner and outer sleeves (2, 3) made of paper material. Each of the flanged end pieces (1, 5) has a tubular portion (7, 7') which is fitted to the ends of the paper sleeves (2, 3). Where inner and outer sleeves (2, 3) are used, the end of the inner sleeve (2) is received by the tubular portion (7), and the iubular portion (7) is inserted into the end of the outer sleeve (3). The use of an inner sleeve (2) prevents excessive play when the spool is fitted to a spool pin (14) of a sewing machine. Thread holding means are also provided in the form of a loose ring (4) which fits around a tubular portion (7) of one of the end pieces (5). A side face (8) of the flange portion (6), opposite the ring (4), is inclined so as to define therewith a wedge-shaped peripheral recess for holding the free end (13) the thread.
摘要:
A storage cabinet, which is useful for storing columns of spools containing sewing thread of different colours and colour shades and of different lengths, provides a column-by-row matrix of dispensing mouths so that articles can be removed, one at a time, from a selected magazine. The articles in each magazine are advanced by a spring-loaded position transducer which provides position data signals representing the content of the magazine. The position data signals are supplied to a microprocessor-controlled display which is connected to a control panel for selecting three modes of operation and for entering keyboard data. In a first mode, a display is provided of any magazine, in a selected column, which has a minimum or less than a minimum content of articles. In a second mode, a serial number of an article is entered on the data keyboard and a display is provided of the contents of a corresponding magazine. In a third mode, a printout is provided which represents an inventory of the contents of each magazine.
