An apparatus for forming a desired belt member in such a manner that a continuous strip material is cut into a plurality of strips each having a predetermined length while the strip material is fed in a direction traversing a conveyer and the cut strips are aligned and spliced on the conveyer while moving the conveyer intermittently. The apparatus is provided with a first guide having a bottom plate for supporting the rear edge of the strip material along a feeding path through which the strip material is fed to a conveyer and a side plate for regulating the rear edge position of the strip material, a second guide having a side plate for regulating the front edge position of the strip material and capable of moving vertically and a splicing press capable of moving vertically along the second guide.

A tire forming system includes a band forming machine, a shaping forming machine, a belt/tread forming machine, means for supplying a band member and means for supplying a belt/tread member. The means for supplying the band member include an inner liner supply means, carcass supply means, band rubber parts supply means and bead supply means. The means for supplying the belt/tread member include belt supply means and tread rubber parts supply means. The means for supplying the band member and the means for supplying the belt/tread member are operative to cooperate with one another to continuously in series form a plurality of tires having different tire sizes.

The object of the present invention is to provide a winding drum for a sheet-like member which can change reliably the range of air sucking intake holes by a simple structure, and to provide a winding drum which can prevent the generation of an unwanted contact mark on the sheet-like member. This winding drum having a hollow portion which is in communication with the intake holes of the drum body, a changeover member which is releasably attached in the hollow portion and which is formed so as to extend along the inner peripheral surface of the hollow portion, and an air passage (second communicating holes, first communicating hole, and hole) which is provided on the changeover member and which communicates intake holes of a predetermined range in the axial direction of the drum body with the suction device when the changeover member is attached in the hollow portion. So the range of air sucking intake holes is switched by changing the changeover member to another changeover member with another air passage.

In a best effort type service of an ATM communication network for circulating an RM cell, a subscriber's switchboard holds the latest route information, and the RM cell is used for short distance communication between the communication terminal and subscriber's switchboard. For a plurality of connections accommodated in the switchboard and using a transmission line or a route in common, information on the allowable transmission rate, the actual transmission rate, the full bandwidth and full input bandwidth of the transmission line or the route, and the number of connections using in common the transmission line are collected and held. A transmission rate acceptable for the caller's terminal is calculated for each connection on the basis of the information. An increase of a memory capacity is restricted by providing a common buffer and managing it by a pointer value. A list of cells which have arrived simultaneously is prepared, and is managed by the pointer value. The cells are sent out at different timings so as not to be discarded. Even when congestion is solved, the restriction is not quickly lifted but control is enforced in consideration of the increment of the cell flow rate immediately after the lift. Convolution calculation is made only once for determining the overall mean cell loss ratio and consequently the number of calculations is reduced.

When bandwidth in an ATM network is controlled so as to increase in accordance with a user request, there is a considerable delay from the occurrence of the request until the bandwidth is actually changed; and there is therefore a need to control the traffic flowing in ATM network transmission paths faster and more flexibly. There is also a need to decrease the probability of overbooking occurring when deciding whether or not to accept a bandwidth change request. Route information that includes information relating to residual bandwidth is therefore collected in advance by subscriber switches that serve terminals. In response to a request from a user, a subscriber switch alone replies rapidly. During this process, the fact that there are a plurality of bandwidth change requests within the same residual bandwidth measurement period, is considered and a portion of the measured residual bandwidth is held for other bandwidth change requests. This enables the delay to be shortened. In addition, it is sufficient if the functions corresponding to the plurality of protocols employed by users are provided at and only at the subscriber switches which directly serve those users, whereby the hardware configuration of the transit switches etc. can be simplified. In addition, bandwidth can be allocated with high precision.
