A removal surface 13 is carried by a support 14 adjustably mounted on rods 15. The roll 21 is driven by contact with the roller 1. When the roll 21 has reached the required size the part 8 with the core 20 of the roll 21 lying thereon is moved downwards by a control (not shown) to the position of Fig. 3 (not shown). A tension roller 18, driven at a higher speed than the roller 1 but in the same direction, stretches the web 3 lying between the roller 1 and the roll 21. Two pistons 17 at the sides of the roller 1 are given an impulse to cause the cutter 16, comprising an electrically heated filament, to cut the web 3. The core 20 is deposited on the surface 13 and slides to the position of Fig.4 (not shown). The carrier 9 contacts a switch 19 which reverses the drive to return the part 8. The carrier 6, Fig.5, is provided with means to store and deliver the new core 23 whilst the roll 21 is being removed. These means comprise a catch 24 pivoted at 25 and normally held in a raised position by a lever 27 lying against a pin 29 on the carrier 9. When the carrier 9 descends the pin 29 descends and the lever 27 pivots downwardly so that, under its own weight or a spring, the catch 24 pivots to the dotted line position and the core 23 slides down onto the part 5. The roller 23 may comprise a wooden core having disposed thereon a cardboard roller 23a provided on both sides with an adhesive band to grip the cut end of the web 3. The winding continues on the core 23 on the part 5 whilst the part 8 is returning.

Abstract: 470,231. Gill drawing-frames. HOLDSWORTH, W. Jan. 30, 1937, No. 2810. Convention date, April 27, 1936. [Class 120 (i)l A device for cleaning the faller teeth 6 in a gill drawing- frame or like machine comprises a wiper 30, Figs. 1 and 4, secured to a faller-bar so as to project therefrom towards the teeth of an adjacent faller-bar in the same row, e.g. the next preceding bar, and adapted to engage and wipe the teeth of the adjacent faller-bar during its transfer movement from one row of faller-bars to another. The wiper 30 is constituted by a strip of resilient material, e.g. an oil resisting rubber-like substance such as synthetic rubber, formed with a thickened marginal portion or bead 31 which is impaled on the teeth 6 and is bent over to press resiliently against the adjacent faller-bar, the fibres on the teeth being wiped from the bases to the tips of the teeth and returned to the sliver M. The wipers 30 also serve to engage and wipe the peripheries of the drawing rollers 10, 11. As applied in an intersecting gill-box having faller-bars 4, 5 with pins or teeth 6, faller screws 2, 3 return screws 16, 17, saddles 20 ... 23, and transfer cams 25, 26, each wiper 30 is folded down as shown in Fig. 5 as the fallers 5 are transferred from the lower screws 17 to the upper screws 3. At the end of its forward stroke each lower faller 5 leaves the saddles 22 and is carried downwardly by the cams 25 and the free edge of the wiper 30 on the next succeeding faller is thereby released and allowed to spring forward against the teeth or pins of the descending faller and to wipe the pins from the bases to the tips. When clear of the teeth the wiper springs outwardly and engages the apron 12 to return the collection of fibres to the sliver M. The action in the upper set is similar.
