Lint produced by abrasion of the warp threads as they pass from the whip roll 18 through the drop wires 20 of a textile loom, falls on to a moving endless belt 24, and means are provided for gathering and collecting the lint into a pack which as it grows in size is permitted to expand into the space left by the receding surface of the warp beam 12 as the warp strands are payed off therefrom to the whip roll 18. As shown, the belt extends between rollers 26, 28 either of which may be driven by any known means on or off the loom. The drive shown is from an oscillating member 68, Fig. 4, of the loom, movement of which through links 64, 62 and a one-way drive 70 rotates the roller 28. The belt rollers are carried by a frame 30 adjustably supported on a loom member 34 by brackets 32, and comprising a cross-piece 36, side arms 44, 48 and links 46 which, by means of bolt, nut and lockwasher combinations 54, 56, enable the frame length, axial relationship of the rollers, and belt tension to be adjusted. Gathering and collecting of the lint from the belt 24 is effected by a clearing roll 78 pivoted to the frame by arms 74 and having a surface 80 with an affinity for lint, whereby as the belt passes under the clearing roll 78, the roll surface becomes covered with lint, gradually forming thereon a sleeve 81 of ever-increasing diameter. Shoes 82 on the free end of the frame 30 ride initially on the outer surface 13 of the warp beam 12 and allow the frame to pivot downwardly (about the axis of roller 28) as the warp is consumed in use, until, when sufficient downward movement has been made to accommodate the lint sleeve 81, further downward movement is arrested by hook members 82. Another arrangement (Figs. 16, 17, 19 and 20) for collecting and storing the lint comprises a series of flexible blades (678, 678a and 678b) which bear against the belt and cause the lint to form into wads which fall into an expandable bag (681) also accommodated in the space formed by the receding surface 13 of the warp beam.

IPC: G05B19/18
Filed: 1968-09-16
Abstract: 1,180,514. Programmed control of machine tools. ING. C. OLIVETTI & C. S.p.A. Sept.16, 1968 [Sept.16, 1967], No.43982/68. Heading G3N. A numerical control device for effecting conjoint control of one or more members of a machine tool or other equipment along one or more axes and about a rotary axis comprises, a programme unit feeding to an interpolating unit the extreme co-ordinates of a displacement along the linear axes, the displacement increment along each said axis for each rotation about the rotary axis and the constant speed of rotation of the member which rotates about the rotary axis, the inter-polating unit operating cyclically to determine displacement increments about the linear and rotary axes, and a rotary position measuring transformer, comparing the present position of the member with respect to the rotary axis with the position computed by the inter-polating unit, delivering an error signal controlling the computation of the inter-polating unit. As shown, a screw blank 3 is secured to the spindle of a machine tool and is rotatable about an axis C, and machined by a tool 8 positioned along the Z-axis by a servo-mechanism SM. Rotation about the C-axis is determined by a rotary position measuring device 1 and displacement of the tool by a Z-axis cyclic linear displacement measuring device 2 producing a series of position zeros at intervals. An inter-polating unit as disclosed in Specification 1,154, 761 is fed by a programming unit 5 and supplies digital positioning orders to digital-to-analog converters 6, 7 providing sine and cosine values to the measuring devices. In order to ensure that the tool 8 follows a screw-thread on the blank 3 the computation of the angle C must be synchronized with the rotation of the blank, the error signal from the device 1 then being a null or zero. The error signal is applied to an amplifier in the inter-polator which supply logic signals when the error exceeds set positive and negative limits. During synchronization no displacement occurs along the Z-axis, the computation of Z-axis signals being initiated, in dependence on the desired thread pitch, when the error signal from the device 1 crosses the position zero from a positive to a negative value. The error signal from the device 2 controls the position of tool 8 retroactively through the servomechanism SM. For a tapered thread displacement the pitch along the transverse axis is also programmed.
